What is A573 Grade 58 (A573 Gr 58) steel plates

The company's main business: ship plate, A573 Grade 58 (A573 Gr 58) steel plates low alloy plate, automobile steel, high-strength plate, pipeline steel, boiler steel plate, weathering plate, wear-resistant plate, bridge plate, pressure vessel plate, steel plate, steel processing, etc. The company takes the implementation of high-end, A573 Grade 58 (A573 Gr 58) steel plates high-quality, deep processing, strengthening the main business, diversified operation, group operation, enterprise transformation and upgrading as its development strategy, and makes all efforts to be your professional A573 Grade 58 (A573 Gr 58) steel plates steel supplier and partner.

High temperature (creep temperature above) boiler steel plate, generally indicates low alloy heat-resistant steel A573 Grade 58 (A573 Gr 58) steel plates, the commonly used are chrome molybdenum steel, chrome molybdenum vanadium steel, chrome molybdenum tungsten steel, etc. For example, 15CrMoG and 12Cr1MoVG boiler steel plate in GB713 and gr 22 and gr 91 boiler steel plate in ASME SA387/SA387M. High temperature boiler steel plate A573 Grade 58 (A573 Gr 58) steel plates is mainly used to manufacture high temperature pressure parts such as high temperature header end cover, steam pipe plug plate, etc.

A573 Grade 58 (A573 Gr 58) steel plates, Wear-resistant steel plate has good corrosion resistance:
The alloy layer of the wear-resistant composite steel plate contains a high percentage of metallic chromium, so it has certain anti-rust and corrosion resistance. It can be used to prevent coal sticking when it is used in coal dropping drums and hoppers.

Corrosion resistance of stainless steel mainly owes to the formation of a very thin, adhesive and translucent chromium oxide film on the surface of stainless steel. Once the film is damaged, the chromium in the stainless steel will react with oxygen in the atmosphere to restore the film quickly. At the same time, the mechanical damage can also generate a protective film quickly to prevent the A573 Grade 58 (A573 Gr 58) steel plates, stainless steel from corrosion.

42CrMo alloy steel A573 Grade 58 (A573 Gr 58) steel plates: 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.
