Which elements in ASTM A285 boiler steel plate

The company attaches great importance to systematic management, and has passed the ASTM A285 boiler steel plate ISO9001 quality management system, ISO14001 environmental management system, OHSAS18001 occupational health and safety management system, and ISO 9001: 2008 certification. Insist on ASTM A285 boiler steel plate quality and promote brand development. The company's physical and chemical testing equipment is fully equipped and the quality management operation is standardized. Since 2002, the national, provincial, and municipal product quality inspection random inspection pass rates are all 100%.

Q345E steel is low-alloy high-strength steel with good low-temperature impact properties. The grade of Q345E steel is composed of three parts: Chinese phonetic alphabet representing yield strength, yield strength value and quality grade symbol. Where: Q is the yield strength; 345 is the yield strength value in MPa; E is the grade (passing the - 40 degree impact test). ASTM A285 boiler steel plate, Q345E steel is mainly used in various welding structures, such as bridges, vehicles, ships, pipelines, boilers, large vessels, power stations, workshops, low-temperature pressure vessels, etc.

Stainless steel plate is a general term for stainless steel plate and acid-resistant steel plate, and is a steel plate with good corrosion resistance and rust resistance on the surface. The surface of ASTM A285 boiler steel plate, stainless steel plate is very smooth and clean. It has high toughness, plasticity, and is not easy to be corroded and rusted. Stainless steel plate has corrosion resistance and high temperature oxidation resistance. Stainless steel is durable, can be stored outdoors for a long time, and will not be damaged in bad weather. Stainless steel plate is not easy to rust, but it is not absolutely not rusty.

Molybdenum is a well known alloy element. Molybdenum can refine the grains of steel material, improve the hardenability and thermal strength, and maintain sufficient strength and creep resistance at high temperature. Adding molybdenum to ASTM A285 boiler steel plate, structural steel can improve mechanical properties. Molybdenum can also restrain the brittleness of alloy steel caused by quenching treatment.

The tensile strength of A36 steel plate is 58-80 Ksi (about 400-550MPa), and the yield strength is 36 Ksi (about 250MPa); the tensile strength of Q235 steel plate is 370-500 MPa, and the yield strength is 235MPa; the tensile strength of SS400 steel plate is 400-510MPa, and the yield strength is 245MPa. For the mechanical properties of ASTM A285 boiler steel plate, SS400 steel plate and Q235 steel plate, the thickness of steel plate is less than 16mm. It can be seen from the above data that ASME A36 and Chinese Q235 are named after the yield strength of the material, while SS400 is named after the tensile strength of the material.
