International stainless steel wire rope marking method is to use the American Iron and Steel Institute to mark a variety of standard three-digit level of wrought stainless steel. Notes: ① austenitic stainless steel with 200 and 300 series of numerals, such as stainless steel wire Xie Gang Which is easy to use, some of the more common austenitic stainless steel is 201, 304, 316 and 310 as a marker. ② ferritic and martensitic stainless steel 400 series is represented by a number. ③ ferritic stainless steel is marked 430 and 446 stainless steel wire Xie Gang Which deal, martensitic stainless steel is 410, 420 and 440C stainless steel wire marker Xie Gang Which is good, two-phase (austenite - ferrite) . ④ stainless steel, precipitation hardening stainless steel and high-alloy iron content of less than 50% usually uses proprietary name or trademark name. Stainless steel wire rope standard classification and grading 1, grade classification: ① national standards GB② industry standards YB③ ④ local standards enterprise standard Q / CB their morphology can be divided into three categories: semi-austenitic precipitation hardening, precipitation hardening martensitic size and precipitation hardening austenitic stainless steel. Included in China's national standard steel grades have 0Cr17Ni7A, 0Cr17Ni4Cu4Nb and 0Cr15Ni7M02Al three kinds of stainless steel wire Xie Gang, it is part of a precipitation hardening semi-austenitic stainless steel. Organizational characteristics of the steel is an austenite plus a volume fraction of 5% to 20% of ferrite during solution or annealed condition. This series of steel after heat treatment or mechanical treatment after deformation of austenite into martensite, and then by aging precipitation hardening to achieve high strength required. This steel has good formability and good weldability, high strength materials can be used in the nuclear industry, aviation and aerospace industries, has been applied. Which benefits Xie Gang stainless steel wire, stainless steel Shengyuan, Xie Gang, stainless steel wire provided by the Dongguan City Shengyuan Stainless. Dongguan Shengyuan Stainless Steel Co.
