According to the production process, stainless steel rods can be divided into three types: hot rolling, forging and cold drawing. The specification of hot-rolled stainless steel round bar is 5.5-250mm. Among them: 5.5-25 mm small stainless steel round bars are mostly supplied in straight strips, often used as steel bars, bolts and various mechanical parts; stainless steel round bars larger than 25 mm are mainly used for manufacturing mechanical parts or as seamless steel pipe billets .

AISI 410 Stainless Steel, SS410 (UNS S41000)
AISI 410 stainless steel is one of the most commonly used martensitic stainless steels. It contains about 12% Cr and therefore provides moderate corrosion resistance. Unlike austenite such as AISI 304 and AISI 316, martensite such as grade 410 is magnetic and can be hardened by heat treatment like carbon steel and low alloy steel. SS410 has good tensile strength, creep and fatigue strength and other mechanical properties, mainly used in steam turbines, jet engines and gas turbines.
Type 420 is basically a high-carbon version of SS410 which provides higher strength. Ferritic stainless steel 430 contains a higher chromium content, so it has higher corrosion resistance.
