This standard ASME SA516 is mainly used to improve the notch toughness important for welding steel plates for pressure vessels. The tensile strength of SA516Gr.60 (HIC) is 415MPa min. The main element content is C Mn Si, P and S control determines its performance. SA516Gr.60 (HIC) chemical composition: C: ≤0.30, Mn: 0.79-1.30, P: ≤0.035, S: ≤0.035, Si: 0.13-0.45. It is a carbon steel material for medium and low temperature pressure vessels.
The company now has ship construction use A131 DH36 structural steel oversea market department, sales and supply department, finance department, logistics department, technical equipment department, quality management department, production department and other departments. The staff with college degree or above accounted for more than 80%, and there were more than ship construction use A131 DH36 structural steel 30 professional and technical personnel. The LSAW pipe production line can produce welded pipes with Φ350-1800mm, wall thickness 6-80mm, and length 2-12m.
The purpose of ship construction use A131 DH36 structural steel quenching is to transform the supercooled austenite into martensite or bainite to obtain a martensite or bainite structure, and then cooperate with tempering at different temperatures to greatly improve the strength, hardness, performance, fatigue strength, toughness, and wear resistance etc. of ship construction use A131 DH36 structural steel. So as to meet the different use requirements of various mechanical parts and tools. Quenching can also help to get the ferromagnetic, corrosion resistance and other special physical and chemical properties of certain special steels.
Boilers with different parameters, different capacities, and different structures have different ship construction use A131 DH36 structural steel, steel consumption rates. Boilers with small capacity and high steam parameters have high steel consumption. Boilers with low steam parameters mainly use low-carbon steel, while boilers with high parameters use a larger amount of heat-resistant alloy steel, and their cost is much higher. In addition, because the once-through boiler has no steam drum or downcomer, steel consumption has also been reduced.
The company specializes in heavy plate cutting, carbon steel pplate processing, carbon plate welding processing and sales of wide and thick steel ship construction use A131 DH36 structural steel plates. It has high-quality CNC steel plate cutting and processing equipment, a professional technical personnel team, and supporting logistics distribution and after-sales service system. BBN company provides customers with solutions at low prices, high quality, and fast response service.
