Stainless steel grades are engineered to provide a wide spectrum of mechanical strength, corrosion resistance, and performance characteristics to meet diverse application requirements. From austenitic and martensitic grades to duplex and precipitation‑hardening stainless steels, these materials are selected based on factors such as corrosion exposure, strength requirements, temperature, and fabrication needs. We supply a broad range of stainless steel grades to support demanding applications across critical industries.
304 Stainless Steel
Type 304 stainless steel contains approximately 18% chromium and 8% nickel and is the most commonly specified stainless steel used throughout the world.
316 Stainless Steel
Type 316 is a chromium nickel austenitic stainless steel containing molybdenum. The molybdenum addition enhances the corrosion resistance over that of 304 in halide environments as well as in reducing acids such as sulfuric and phosphoric acid.
410 QDT Stainless Steel
Type 410 QDT is a quenched and double tempered, 12 percent chromium martensitic stainless steel suitable for general purpose applications that is corrosion resistant to fresh water and mild acids and alkalies.
416 Stainless Steel
Type 416 is a free machining high hardenability martensitic stainless steel with excellent machinability, reasonable strength and corrosion resistance.
420 Stainless Steel
Type 420 is a hardenable, straight-chromium stainless steel which combines superior wear resistance of high carbon alloys with the excellent corrosion resistance of chromium stainless steels.
Duplex 2205 Stainless Steel
2205 stainless steel (UNS S31803 and/or S32205) is a nitrogen-enhanced duplex stainless steel alloy and is the most widely used of the duplex stainless steels.
Super Duplex 2507 Stainless Steel
2507 stainless steel was designed for demanding applications which require exceptional strength and corrosion resistance, such as chemical process, petrochemical, and seawater equipment.
A-286 Stainless Steel
A-286 is a Ni-Cr austenitic precipitation-hardened iron-based steel that is one of the original superalloys. It has been used for applications requiring high strength and corrosion resistance up to 1,300°F (704°C), and for cryogenic applications.
17-4 PH® Stainless Steel
17-4 PH® is a martensitic precipitation hardening stainless steel offering high strength and hardness along with moderate corrosion resistance up to 600˚F.
XM-19 Stainless Steel
Nitronic 50 (XM-19) is a high strength and corrosion resistant austenitic stainless steel.
Nitronic 50 (XM-19)
Nitronic 50 is a high strength and corrosion resistant austenitic stainless steel that has nearly double the yield strength of 304 and 316 stainless steel with better corrosion resistance than 317L stainless steel.
Nitronic 60
Nitronic 60 is known for its excellent galling resistance, even at elevated temperatures. The additions of 4% silicon and 8% manganese inhibit wear, galling, and fretting.
