SA633 Gr E carbon steel material,Main product: low-temperature boilerplate, pressure vessel plate, SA633 Gr E carbon steel material high-strength plate, Q245R, Q345R grade, Q420C, Q690C, Q690D, Q345R steel plate, A516 Gr 70, A572 Grade 50 equivalent. The company's long-term and stable cooperation relationship with major steel mills ensures that the company provides excellent products and high-quality services to new and old customers, and strives to build a first-class marketing system in the industry.

In the manufacturing process of boiler pressure components, raw materials must undergo complex processing deformation and welding, so the steel used to manufacture the boiler must also have good process performance. All materials SA633 Gr E carbon steel material used to manufacture pressure parts must conform to the relevant national standards for boiler steel. The defects such as delamination, non-metallic inclusion, porosity and looseness in the steel shall be as few as possible, and white spots and cracks are not allowed.SA633 Gr E carbon steel material

SA633 Gr E carbon steel material,Quenching and tempering (QT) is a double heat treatment process of quenching and high temperature tempering. In general, medium carbon steel and medium carbon alloy steel often need quenching and tempering treatment. Quenching and tempering can make iron and steel parts obtain a good combination of strength and toughness, with high strength, excellent toughness, plasticity, cutting performance, etc. Some alloy steel or low alloy steel must be quenched and tempered to obtain good comprehensive properties. These steels can also be called quenched and tempered steels.

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.

After-sales service team is a key department to test the steel quality. Product quality is always the foundation of our survival and development. The company's full inspection from raw materials to finished products; and implements standardized, scientific, and strict internal quality control and management systems in accordance with the process flow during the production process; products can only leave the factory if qualified, and follow-up problem solving systems are implemented in after-sales services to guarantee the customers’ interest.
