SA572Gr50钢板硬度试验
The ability of a metal material to resist the indentation of an indenter (a hardened steel ball or a diamond indenter with a 1200 conical or angular cone) is called hardness. According to the different test methods and application ranges, hardness can be divided into Brinell hardness, Rockwell hardness, Vickers hardness, shore hardness, microhardness, high temperature hardness, etc. Metallurgical products are commonly used with Brinell and Rockwell hardness.
SA572Gr50钢板企业标准(QBQB)
The steel grade in the SA572Gr50 steel plate enterprise standard can be roughly divided into three sources: that is, transplanted from Japan JIS standard, Germany DIN standard and newly developed steel grade. The steel number transplanted from the Japan JIS standard is often S (Steel) in the first place; Steel numbers ported from the DIN standard, which usually start with ST ("steel" in Stahl in German); The steel number developed by Baosteel is often the first B of Baosteel's pinyin.
SA572Gr50 Steel Plate Structural Steel Plate for Hot Rolling, Cold Continuous Rolling Steel and Steel Strip Structural Steel is generally classified by strength, and the number in the steel number often represents the lowest value of tensile strength. Because this type of steel is often used to make structural parts, it is called structural steel. The strengthening mechanism of structural steel tends to reduce carbon and increase manganese solution strengthened ferrite, refine pearlite and add microalloy precipitation strengthening, precipitation strengthening and fine-grain strengthening to ensure that the strength is improved while still maintaining good toughness and plasticity indexes and good welding performance.
SA572Gr50 steel plate is widely used in engineering structures, such as building steel structures, construction machinery, mining and mountain machinery, truck trucks, bridges, pressure vessels, etc., especially for construction and construction machinery components that require good weldability and toughness.
