It has laid a foundation for the development of our A588 grade A HSLA steel plate steel market and improved the control of steel plate production quality.
ASTM Corten B steel is a hot-rolled structural steel product with better atmospheric corrosion resistance under Technical delivery conditions. ASTM Corten B steel conforms to ASTM standard, with yield strength of 355MPa and 345mpa, and the A588 grade A HSLA steel plate yield strength depends on the thickness. The tensile strength of ASTM Corten B steel is 470-630 MPa.
Q235 steel grades cover Q235A, Q235B, Q235C and Q235D. Other than Q235A, the other three Q235 steel grades needs impact test. Charpy V-notch specimen is used for impact toughness test. The impact toughness index is Akv. Q235 steel plates are widely used because of its moderate carbon content, good comprehensive performance, good coordination of strength, plasticity and welding performance.
A588 grade A HSLA steel plate, Special thick steel plate cutting needs to be preheated in advance. Some steel plates are prone to cracks after entering the cutting process, sometimes that is because the temperature is too low, and it is necessary to perform pre-heat treatment in advance for such cases. The staff can preheat the steel plates first, so that the temperature of the steel plates will gradually increase, and then the flame gun can be used to cut. The probability of cracks in the cut material is very low, and the quality of the steel plate is also guaranteed.
42CrMo alloy steel A588 grade A HSLA steel plate: low temperature tempering welding performance thermal processing The heating temperature is 1150 ~1200°C, the starting temperature is 1130 ~1180°C, the ending temperature is> 850°C, and when φ> 50mm, slow cooling. The normalizing temperature is 850~900°C, and the furnace is air cooled. High temperature tempering: Tempering temperature is 680~700°C, and it is air-cooled from the furnace.
