steel coil S355J0W complete specification overheat sensitivity

Beijing machining center has more than 1000 employees, including 360 technicians, 28 engineers, 6 senior welders, 15 professional welders, 52 bachelor's degree, 3 doctor's degree, and 8 R & D team. It is a professional steel coil S355J0W complete specification production team combining theory and practice. With an annual output of 80000 tons, looking forward to the future, our company continues to strengthen the advantages of steel coil S355J0W complete specification leading suppliers in the four steel fields of steel plate, steel pipe, stainless steel and special steel.

27SiMn steel plate has high strength and wear resistance, high hardenability, good machinability, moderate cold deformation plasticity and weldability. In addition, the toughness of 27SiMn steel does not decrease much during heat treatment, but it has quite high strength and wear resistance, especially when water quenching still has high toughness; but this steel is highly sensitive to white spots and has temper brittleness during heat treatment. Tendency and sensitivity to overheating.

The large diameter cold drawn seamless steel pipe is a steel pipe with an outer diameter of more than 1000mm. The large diameter seamless steel pipe is made of steel ingot or solid billet through perforation and then hot rolling, cold rolling or cold drawing. If they are long, they need to remove the redundant parts, that is, cut them out. Their length steel coil S355J0W complete specification is suitable for the length required by the construction of steel pipes.

steel coil S355J0W complete specification, Hot-rolled steel coils are made of steel billets, which are made into strip steel by the rough rolling mill and the finishing mill after heating. The hr steel strip from the rolling mill behind the finishing rolling is cooled to a set temperature by laminar flow, and then coiled into a steel coil by the coiler. The cooled steel coil will undergo different processes according to the different needs of users, and is processed into steel plates, flat coils and slit steel strip products.

T11 steel is a steel grade produced according to American Standard ASTM A213. T11 steel is used for boiler, superheater and heat exchanger tubes with minimum wall thickness. Chemical composition of ASTM A213 T11 steel: C 0.05-0.15, Si 0.50-1.00, Mn 0.30-0.60, P, S ≤ 0.025, Cr 1.00-1.50, Mo 0.44-0.65. Mechanical properties of ASTM A213 T11 steel: tensile strength ≥ 415 Mpa, yield strength ≥ 170 Mpa, elongation ≥ 30%. The main ASTM A213 steel pipe grades are A213 T11, A213 T12, A213 T22, steel coil S355J0W complete specification, etc.

The boiler steel plates are among our main products. Other than standard size boiler steel plates, we also provide steel coil S355J0W complete specification cutting, bending and so on processing to change plate size and shape according to your requirements. Welcome to consult us about steel coil S355J0W complete specification ASTM A204 grade B properties, SA 516 gr 70 temperature range, ASTM A285 grade C chemical composition, boiler steel price and so on questions and ask for offer.

The after-sales service personnel understand the user's ideas and needs in detail, and stand on the other side's position and interests. Actively communicate with users and help them solve practical problems. This not only solves the service problem, but also improves the customer's trust in the company.
