TP304 / TP304L
Product Information
304 provides useful resistance to corrosion in many environments ranging from moderately reducing to moderately oxidizing. Through the controlled addition of nitrogen, it is common for 304L to meet the mechanical properties of 304 straight grade. As a result, most products are dual certified as 304 and 304/304L.

TP316 / TP316L
Product Information
With the addition of molybdenum, grades 316 and 316L stainless steel were developed to offer improved corrosion resistance compared to alloy 304/L. The increased performance of this austenitic chromium-nickel stainless makes it better suited for environments rich in salt air and chloride. Additionally, the low carbon content makes the alloy 316/L easy to weld.

TP321 / TP321H
Product Information
TP321/H is a standard austenitic 18/8 chromium-nickel alloy with the addition of titanium, making it an excellent choice in elevated-temperature environments. The titanium stabilizes the material — removing its susceptibility to intergranular corrosion. 321 is therefore the stainless steel of choice for working environments up to 900°C.

TP310S / TP310H
Product Information
310S (UNS S31008) is the low-carbon version of the alloy, utilized for ease of fabrication. 310H (UNS S31009) is a high-carbon modification developed for enhanced creep resistance. In most instances the grain size and carbon content of the plate can meet both 310S and 310H requirements — making it ideal for high-temperature furnace and heat treatment service.

TP410
Product Information
Type 410 is hardenable, straight-chromium stainless that combines the superior wear resistance of high-carbon alloys with the excellent corrosion resistance of chromium stainless steels. Oil quenching from temperatures between 1800°F to 1950°F (982–1066°C) produces the highest strength, wear resistance, and corrosion resistance. Used where strength, hardness, and wear resistance must combine with corrosion resistance.

S31803 (COLDUPLEX) is a standard grade of duplex stainless steel based on 22% chromium and 5% nickel — often referred to as Alloy 2205. The most widely used duplex grade due to its combination of very good general corrosion resistance and high strength. Not generally suitable above 300°C due to brittle micro-constituent precipitation, nor below -50°C due to ductile-to-brittle transition.
