Iron and steel is the material basis of production and expanded reproduction in modern society. From simple manual labor tools to complex aerospace technology, no industrial sector has a direct and indirect relationship with the steel industry. Among them, the tensile strength analysis of stainless steel rods has the following methods:
Chemical composition analysis: composition detection, brand identification, material identification, full composition analysis, routine chemical element composition detection, mechanical property test: tensile test (yield strength, tensile strength, elongation, reduction of area, etc.), bending test, room temperature impact, low temperature impact, hardness test (HV Vickers hardness, HRC Rockwell hardness, Hb Brinell hardness)
Corrosion resistance test: intergranular corrosion, iron chloride corrosion test of dual phase steel, NSS neutral salt spray, AASs acid salt spray test, CASS copper ion accelerated salt spray test, CCT circulating salt spray corrosion test
Metallographic analysis: Determination of average grain size, comprehensive rating of non-metallic inclusions, microscopic evaluation of non-metallic inclusions, examination of metallographic structure, examination of microstructure, observation of forging flow line of forgings, rating of large carbide of tool steel, eutectic carbide non-uniformity, decarburization, determination of carbide grain size, macrostructure of bearing steel, depth of nitrided layer, depth of hardened layer, evaluation of eutectic carbide non-uniformity of steel
