Our company was founded in 2000, which initially committed to providing high-quality steel CCS E40 chemical tanker steel products for China's rapid infrastructure construction. With the advantages of steel resources and good reputation in the domestic market, combined with the huge demand for steel in the international market, we began to export CCS E40 chemical tanker steel steel to the international market, opening up the international steel market.
Our CCS E40 chemical tanker steel, A572Gr50 plates are produced with thickness up to 100mm. A572Gr50 low-alloy high-strength structural steel plate is widely used in engineering structures, such as construction steel structures, construction machinery, mine mountain machinery, trucks, bridges, pressure vessels. This kind of steel is especially used for those that require good weldability and toughness Construction and construction machinery parts.
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.
Quenching is a heat treatment process in which steel parts are heated to above the critical temperature, and after proper heat preservation, the parts are quickly cooled to room temperature in water or oil, so that martensite transformation occurs. The hardness of the quenched CCS E40 chemical tanker steel increases sharply. Quenching is to prepare the organization for adjusting and improving the performance of CCS E40 chemical tanker steel during tempering, while tempering determines the performance and life of the workpiece.
CCS E40 chemical tanker steel, S235JR VS S275JR VS S355JR plates in yield strength: For plate thickness ≤16mm, the min. yield strength of S235JR plates is 235 Mpa, S275JR plates is 275 Mpa, S355JR plates is 355 Mpa. The yield strength of S235JR S275JR S355JR plates reduces with the increasing of plate thickness. S235JR VS S275JR VS S355JR plates in tensile strength: For plate thickness 3-100mm, the tensile strength of S235JR plates is 360-510 Mpa, S275JR plates is 410-560 Mpa, S355JR plates is 470-630 Mpa. For plate thickness 100-150mm, the tensile strength of S235JR plates is 350-500 Mpa, S275JR plates is 400-540 Mpa, S355JR plates is 450-600 Mpa.
Customer first, reputation first, high-quality and perfect after-sales service is the extension of our product value and an important guarantee for the interests of customers. The purpose of our CCS E40 chemical tanker steel service quality management system is to establish and constantly improve a scientific, reasonable and efficient service quality management system, and complete the after-sales service quality guarantee work of customers fairly, accurately and timely, For our company's CCS E40 chemical tanker steel customer service to establish a good, comprehensive, full service system.
