When processing molds, because the molds made of stainless steel flange are widely used, and the working conditions of various molds made of stainless steel flange are very different, the range of materials used for manufacturing molds made of stainless steel flange is very wide, and the mold steel is the most widely used in mold materials. From general carbon structural steel, carbon tool steel, alloy structural steel, alloy tool steel, spring steel made of stainless steel flange, high-speed tool steel, stainless heat-resistant steel to maraging steel, powder high-speed steel and powder high-alloy die steel to meet the needs of special dies. Die steel made of stainless steel flange can be generally divided into three categories: cold working die steel, hot working die steel and plastic die steel.
Compared with austenitic stainless steel made of stainless steel flange, it has high strength and significantly improved resistance to intergranular corrosion and chloride stress corrosion. Duplex stainless steel has excellent pitting corrosion resistance and is also a nickel saving stainless steel. stainless steel flanges have clear requirements. Common brands are 06cr19ni10, 022cr17ni12mo2, and the numerical codes are s30408, s31603, etc. It is mainly used for sanitary equipment such as food machinery and pharmaceutical machinery.
B. Steel strip made of stainless steel flange
① After the spring is delivered in cold rolling state, it needs to be tempered at low temperature to eliminate stress of stainless steel flange.
② After the spring is delivered in quenched and tempered state, it needs to be tempered at low temperature to remove the stress.
③ Quenching and tempering are required after the springs are delivered in the annealing state
C. Cold drawn steel of of stainless steel flange
The steel of of stainless steel flange delivered in annealed state is cold formed into springs, which are then quenched and tempered.
