Jinan Yasunobu stainless steel guardrail _202 _ Heze stainless steel rails provided by Jinan Yasunobu stainless steel. We are Jinan Yasunobu Stainless Steel Co., Ltd. (www.jntaixin.com) at: Jinan specializes in: stainless steel rails, stainless Baolan, stainless steel sun roof, stainless steel guardrail shelters material stainless steel processing one day, they experiment a lot containing chromium The domestic steel, after abrasion test to identify this alloy does not wear, shows this can not manufacture firearms, so they record the results, to the corner fling trouble. 202 stainless steel guardrail day a few months later, an assistant holding a piece of steel Zeng light watt light came on Bray Hurley said excitedly: "Sir, this is what I found when cleaning the warehouse sent Mr. Mao La alloy Steel, if you experiment to see if it has any special role in the end! "" Good! "Bray Hurley looked glittering steel, said happily. Precipitation hardening stainless austenitic or martensitic matrix organization, precipitation hardening stainless steel grades are commonly used 04Cr13Ni8Mo2Al so on. Its through precipitation hardening (also known as age-hardening) process to make it hard (strong) of stainless steel. Stainless steel, high strength martensitic stainless steel sterilizer stainless steel rails, but poor ductility and weldability. Martensitic stainless steel commonly used grades are 1Cr13,3Cr13 etc., due to the higher carbon content, it has a high strength, hardness and wear resistance, corrosion resistance, but somewhat less, the requirements for high mechanical properties, corrosion resistance Some of the general requirements on parts, such as springs, turbine blades, valves and other hydraulic machines. Such steel is after quenching, tempering use. Forging, stamping required after annealing
