How can I tell if my stainless steel is 304 or 316?
No, 301 can’t be hardened by heat treatment. You can anneal it, and remove any hardening you got from cold working. But it is an austenitic stainless steel, NOT a martensitic, and only the martensitics can be hardened by heat treatment.
What Is The Difference Between 301 & 304 Stainless Steel?
Type 304—the most common grade; the traditional 18/eight (18% chromium, 8% nickel) stainless steel. Outside of the US it’s commonly generally known as “A2 stainless steel”, in accordance with ISO 3506 (not to be confused with A2 tool steel). For example, a 1060 steel is a plain-carbon steel containing 0.60 wt% C. Carbon is a needed alloying factor in all kinds of metal as it makes brittle iron malleable and ductile.
The mechanical and physical properties of kind 301 stainless steel make it an ideal materials for a mess of purposes each for industrial and shopper products. These including Springs, Gaskets, Shims, Fasteners, Tools, Blades, Automotive Parts, Aerospace Components, Kitchen Utensils, and Tableware, Electrical Components and lots of others. Full Hard Cold Rolled – Type (chrome-nickel) Stainless Steel permits chilly working to the ideal combination of mechanical properties desired for springs. Its unique mixture of hardness and toughness makes for higher forming quality in this Full Hard Temper plus increased fatigue life within the finished spring.
For example, should you have been to weld or laser-reduce a piece of 301 stainless-steel, you would be extra likely to see signs of corrosion within the heat-affected zones than you would in a piece of 304 alloy handled in the identical method. This is due to chromium carbide precipitation, which depletes the chromium in the warmth-affected areas. Most stainless steel alloys have good or wonderful resistance to corrosion in normal circumstances.
How do you heat treat 304 stainless steel?
Stainless steel is a clean, durable, corrosion resistant material with a design life expectancy of over fifty years.
- It is the addition of chromium that gives the metal its unique stainless, corrosion resisting properties.
- The key distinction that makes them different is the addition of molybdenum, an alloy which drastically enhances corrosion resistance, especially for extra saline or chloride-exposed environments.
- Stainless steel is essentially a low carbon steel which incorporates chromium of 10% or extra by weight.
- Austenitic 304 and 316 stainless steels are thought of surgical or medical-grade stainless steels, they are probably the most commons stainless steels.

Our stainless production range
However, grade 304 stainless-steel gets extra chromium and nickel than grade 301 does. This tends to make grade 304 stainless costlier than grade 301 is.
Stainless metal alloys are likely to possess a powerful, however thin, layer of oxide that prevents rusting, therefore the name “stainless” steel. It is not heat-treatable for hardening purposes and is non-magnetic as annealed, but slightly magnetic following cold working. Type 301 possesses good warmth and corrosion resistance and welds easily. PSW shares Type 301 chrome steel in the 1/4 hard, half exhausting, 3/four hard, full exhausting, and extra exhausting tempers. Precision Steel carries a listing of 301 full onerous tempered chrome steel in sheets and coils.
Grade 304 stainless steel, by comparison, can only take up to ninety ksi of strain before experiencing mechanical failure. This means that at room temperature, a basket manufactured from grade 301 stainless steel can take up to 33% extra stress than an analogous basket created from grade 304 alloy.
Half-exhausting 304 Stainless Steel
Type S— is a highly alloyed austenitic stainless steel used for high temperature utility. The excessive chromium and nickel content material give the steel glorious oxidation resistance as well as high strength at excessive temperature.
We have thousands tons stock of stainless steel sheet and coil with various size and grade,mainly include austenitic stainless steel, martens stainless steel (including precipitation hardened stainless steel sheet & coil), ferritic stainless steel, and duplex stainless steel.
