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.

Characteristics of Stainless Steel Sheet and Plate:
High corrosion resistance
High strength
High toughness and impact resistance
Temperature resistance
High workability, including machining, stamping, fabricating and welding
Smooth surface finish that can be easily clean

Good Moderate to good corrosion resistance in quite a lot of environments. Service to +600°F (+316°C).F5325%Chrome, 7%Nickel 4-half of%MolyF53 is an excellent duplex stainless-steel. This material has glorious corrosion resistance in quite a lot of environments. I am not conscious that there’s a vital distinction within the corrosion resistance of 1 over the other. The primary cause for using an L grade of chrome steel is that it will scale back the tendency of the material to crack after welding.

We produce ASTM/ASME Grade 304, Grade 304L,304h, 316, 316L, 316H, 316TI, 321, 321H, 309S, 309H, 310S, 310H, 410S, 2205, 904L, 2507, 254, gh3030, 625, 253MA, S30815, 317L, Type 317, 316lN, 8020, 800, 800H, C276, S32304 and others special requirement stainless steel grade.

The 316L is more ductile when annealed, and is markedly extra corrosion resistant, especially after welding. 316L is rather more weld friendly than 316, as it’s much less vulnerable to intergranular corrosion, after welding or air service up to 1600 °F °F , because of carbide precipitation. In 316 carbide precipitation will happen between 900 F-1070 F after 9 hours, whereas 316L will precipitate carbides between 900 °F °F after 181 hours, 316L showing much more resistance to sensitization.

These grades for forged valves bodies match carbon steel pipes in grades A53, A106, API 5L. Let’s return to the concern about using CF8M in nitric acid services. As a end result, in terms of valves, it is just pure to pick CF8 pondering will probably be less expensive than CF8M. For reasons mentioned beforehand, this is probably not true. Therefore, the remaining question is whether CF8M is appropriate for nitric acid service.

As a result, some reactive alloy foundries will worth grade 12 titanium the same because the more corrosion-resistant palladium grades. In this case, there may be no price benefit in specifying grade 12 solid titanium valves. The major distinction is the decrease carbon content, 316 being 0.030, 316L being as little as 0.016. Other elements are also somewhat decrease,similar to sulfur, phosphorus and copper.

Increased ferrite can scale back influence toughness at ultra-low temperatures (under -300 F) and after exposure to high temperatures although the latter is uncommon. This specification covers iron-chromium and iron-chromium-nickel alloy castings for general corrosion-resistant application.

Cross Reference Chart: Astm Cast Vs. Forged Materials

The grades of those castings symbolize kinds of alloy castings suitable for broad ranges of application which are intended for a wide variety of corrosion environments. The steel shall be made by the electric furnace course of with or with out separate refining such as argon-oxygen decarburization.
