CCS EH36,CCS/EH36 and CCSEH36 steel is a high strength shipbuilding steel plate. We have 200tons RA32 oil supply vessel steel, CCS Grade EH36 hot rolled plates and sheets in our warehouse. Our available stock has CCS EH36 steel size and specification: 5*2000*9000, 13*1500*6000, 46*2500*7200, 33*2250*6400, 5*2000*8000, 33*1520*7250, 40*1500*6000, 5*2000*10000, 44*1800*10550, 90*1650*6400mm. Our ship steel plate can be supplied with thickness up to 200mm.
The purpose of RA32 oil supply vessel 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 RA32 oil supply vessel 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.
The qualified flat steel has sufficiently high high temperature strength and high temperature plasticity. Therefore, RA32 oil supply vessel steel flat steel is not only required to have high enough normal temperature and instantaneous high temperature tensile strength and plasticity, but also long-term strength and long-term plasticity to ensure long-term safe work at high temperatures, especially under creep leakage conditions. The product thickness is 8-50mm, width 150-625mm, length 5-15m。
In order to obtain the seamless tube with smaller size and better quality, the method of cold rolling, cold drawing or the combination of the two must be used. Cold rolling is usually carried out on a two high mill, and RA32 oil supply vessel steel pipes are rolled in a circular pass composed of a variable cross-section circular groove and a fixed conical head. Cold drawing is usually carried out on single chain or double chain cold drawing machines of 0.5-100t.
