All stainless steels grades are resistant to high-temperature, this post will guide you to choose the best grade of SS high-temperature applications. 13-8 Stainless Steel 13-8 is a low carbon stainless steel with high tensile strength and corrosion resistance. The four categories are: Plain carbon steel - 10xx series (containing 1.00% Mn maximum) Resulfurized carbon steel- 11xx series Resulfurized and rephosphorized carbon steel - 12xx series Non-resulfurized high-manganese - 15xx series (containing up to 1.65% Mn) While both nickel and stainless steel have relatively high melting points, they are best used as alloys . It is not oxidized and deformed under the temperature of 1080 throughout the year. 436. Martensitic Stainless Steel Specification Aisi 410 Stainless Steel Aisi 416 Stainless Steel Aisi 419 Stainless Steel AISI 446C Stainless Steel Aisi 420 Stainless Steel Aisi 429 Stainless Steel AISI 409S Stainless Steel AISI 416C Stainless Steel AISI 430F Stainless Steel The second most common reason stainless steels are used is for their high temperature properties; stainless steels can be found in applications where high temperature oxidation resistance is necessary, and in other applications where high temperature strength is required. Stainless steel performs comparatively better than other carbon steels at higher temperatures. . High temperature austenitic grades The high temperature austenitic stainless steels are designed primarily for use at temperatures exceeding 550 C, i.e. As for the low temperature, the performance of ferritic types is similar to martensitic types. Type 304, the most common grade of stainless-steel with 18% chromium, is resistant to approximately 870 C (1,600 F). It is an excellent material for headers and exhaust systems, or any application where high heat is encountered. Type 309 has the same machining properties as Type 304, and can be roll formed, stamped, and drawn easily.
