300 Series Stainless Steel Wire

300 Series Stainless Steel Wire

Spring makers, fastener manufacturers, and wire formers use 300 series stainless steel wire when corrosion resistance and strength are important product features.  Gibbs provides many stainless wire alloys including the most commonly used grades:  
    • 302
    • 304 
    • 316
300 series stainless steel is also sometimes referred to as 18-8 grades.  All 300 grades are austenitic.  Austenitic grades will not gain strength after heat treatment. They gain their tensile and yield strength by cold working or drawing. If hardening by heat treatment is required 400 series stainless wire should be considered.
302, 304, and 316 stainless steel wire is used for countless applications where high strength and corrosion resistance are required.  For added corrosion resistance 316 may be selected.  It is lesser in strength than 302 but it offers improved corrosion characteristics due to the added Molybdenum.
Common industries relying on 300 series stainless wire:
    • Automotive
    • Aerospace
    • Chemical Processing
    • Commercial Products
    • Electronics
    • Machinery
    • Medical
    • Oil & Gas
    • Recreational Vehicles
Many coatings and finishes are available including Bright, Soap, and Nickel.  Coatings are added for drawing purposes and lubricity for many processes including spring coilers.  Bright wire or “diamond drawn” is typically supplied under 0.025” diameter and often used for medical applications
Common specifications for 300 series wire:
    • ASTM A 313
    • SAE J230
    • AMS 5688
    • SUS304 WPB
All 300 grades can be supplied as Spring Temper, ¼ hard, ½ hard, ¾ hard and fully annealed.  Gibbs can provide custom-drawn wire to your specific tensile range.
Most 300 series wire is rated for maximum operating temperatures of 400 to 450 degrees (check specifications by alloy).
Much of the wire Gibbs provides to the industries noted above is used to manufacture springs.  When springs are made they go through a spring coiling process.  That process adds stress to the formed spring.  Most manufacturers stress-relieve their springs after forming.  Stress-relieving reduces the work-hardened stresses making the spring stronger. Many spring makers include this operation in-line with their coiling operation.
After coiling and stress relieving, the springs may also be passivated. The purpose of passivating is to protect the invisible oxide film that completely covers the surface of the parts by removing surface contamination so that the protective film layer is not interrupted. Passivating is done by immersing the parts in a nitric acid solution.
Gibbs is a premier supplier of tempered stainless steel wire in the US, Canada, and Mexico.  In addition to 300 series, we offer PH grades, 400 series, carbon steel, nickel alloys, specialty metals, cobalt alloys, and more.  For more information or to request a quote:  CONTACT US

    Our thoughts on the closing of ASW/Pengg

    Our thoughts on the closing of ASW/Pengg.

    We were saddened to see that ASW/Pengg is closing.  We have enjoyed working with this fine group of people since their inception.  They were both a competitor and a supplier.  In both cases, we always found that they operated with the highest degree of integrity and class.  They sold quality products by a staff of dedicated professionals to both spring manufacturers and distributors.  We wish everyone involved with them the very best.

    We know that their closure has many customers concerned about their supply options going forward.  The rest of this message is to assure you that Gibbs can immediately fill your needs in this regard.

    Gibbs® inventories a vast amount of spring wire including Chrome Silicon Valve and Commercial Quality, as well as, Chrome Vanadium Valve and Commercial Quality. 

    Chrome Silicon Commercial Quality (.019”-.625”) ASTM-A401

    Chrome Silicon Valve Quality (.0197” – .331”) ASTM-A877

    Chrome Vanadium Commercial (.207”-.625”) ASTM-A231

    Chrome Vanadium Valve (.080” -.362”) ASTM-A232

    Helpful Tips for Social Distancing

    Helpful Tips for Social Distancing

    Most Americans are advised to social distance or have been required to shelter in place. Shopping for necessities can pose a real challenge. There are many delivery services available currently from most chain stores for all of the items you need. 

    While you use the list below to help make distancing easier, let’s remember others that may need help. Communities must come together in times of crisis. If we each help one person, we have made a big difference. We can remain safe and at a distance while helping those in need:

      • Donate to your favorite charity or church, they are struggling as donations wane.
      • Buy local. Order take-out weekly or buy a gift card from your favorite restaurant or store. It will help local businesses to stay afloat.
      • Call your elderly neighbors to see if they have the items they need.  Older people may not be as tech-savvy and may not know How to Shelter in Place Like a Prothey can get groceries and prescriptions delivered.  

    American’s come together in times of crisis. We all need to do our part. We can make a difference even though we’re at a distance.

    Here are some tips to help you avoid crowds and public places and still get everything you need.  This post is meant for informational purposes only and is not intended to endorse any particular brand.


    Many national brands and local stores deliver. For my area, I use Peapod https://www.peapod.com/ and Prime Now https://primenow.amazon.com/, delivering for Whole Foods. Both apps can be downloaded through the App Store for the iPhone or Google Play for Android. You may prepay by credit or debit card and the groceries are left on your porch/doorstep. There does not need to be *direct contact with the delivery person if you prepay.

    There are many items currently out of stock. You may want to enable “ok to substitute” if you don’t have brand preferences. Delivery charges may apply and some services offer tipping options which can reduce face to face contact with the delivery person. Use coupons? Many services allow you to submit product coupons when buying online. *See CDC guidelines for surface cleaning of all surfaces/products you come in contact with which may include grocery items


    Don’t cook? Most restaurants are offering delivery service or curbside pickup. Many that did not traditionally offer delivery are now because of the shutdown. There are also options like Uber Eats and DoorDash®. They are third party companies that pick up and deliver to you. The apps can be found on the App Store for iPhone or via Google Play for Androids. Prepay via credit card and include tips in payment when possible to *minimize face to face contact. *Use CDC guidelines for sanitizing surfaces of various types of packaging.


    Use online pharmacy apps. Ask for 90-day supplies when possible. My local CVS store will deliver any item in the store including prescriptions. See CDC guidelines for surface cleaning of all surfaces/products you come in contact with including pharmacy items. The corona lives on various surfaces for extended periods. It may be recommended you sanitize pharmacy products & packaging.


    Exercise can be a challenge if you are used to going to a gym. Some people live in areas where they can get outside safely for a run or walk 6 feet or further from others but, some are ‘shelter in place’ with no outdoor activities allowed. There are many online downloadable exercise videos. I subscribe to the Yoga Channel. Many are free and some have a fee.  Remember if you don’t already exercise you’ll want to discuss it with your doctor before starting.


    There are alcohol delivery services. I had to double-check but in most areas, it’s considered an essential service!


    I must confess I’ve never ‘gamed’ but, this might be the right time to try online gaming. There are hundreds of online game streaming services that families can utilize for entertainment.


    And lastly, Amazon is a source for countless products. If you choose the paid version called “Amazon Prime” you get free delivery on many items. You can buy groceries, housewares, personal items, and access to Prime TV. They also offer Audible, an audiobook service for those that prefer to listen to their favorite books.


    Stay connected with friends and family for free while distancing. Use Zoom.com to video chat with friends and family. Video chats are free for up to 40 minutes per call. Use the ‘gallery’ function to see everyone on the call in one view.


    The link to the CDC website for additional information. The information changes and evolves daily. Check back to this link regularly for updates.
