What is the effect of 30MnB5 tensile strength ksi surface treatment on its properties

Based on the main business of iron and steel, we are committed to producing high-quality, green and efficient steel products. The main steel products are medium and 30MnB5 tensile strength ksi heavy plate, hot rolled coil, section steel, steel tube, etc., which are widely used in automobile, oil, railway, bridge, construction, electricity, transportation, machinery, shipbuilding and other important fields. Our steel products are exported 30MnB5 tensile strength ksi to Indonesia, Bangladesh, Myanmar, Iran, Brazil, Mexico, UAE, Iraq, etc Egypt, Mozambique, Ukraine and other dozens of countries and regions.

Boiler steel plates are mainly used to manufacture various boilers and important accessories. Because the boiler steel plate is working under medium temperature (below 350°C) and high pressure, in addition to high pressure, it is also subject to impact, fatigue load and water and gas corrosion. It is required to ensure a certain strength and also have good welding and cold bending performance. Common grades: Q245R, A515 Grade 55, A515 Grade 60, 30MnB5 tensile strength ksi, A516 Grade 65, A516 Grade 70.

Main uses of 30MnB5 tensile strength ksi, special steel. First, special steel is used for bearing manufacturing. Second, the special steel is used for mold manufacturing, which can withstand high temperature very well, and has excellent repeated use performance, which makes the mold quality excellent also. Third, the special steel is used in the manufacture of spring plates, and the chassis of some cars need to use the spring plate, which has good elasticity and flexibility. Fourth, the special steel is used in the aerospace industry. Fifth, the special steel is used to manufacture hardware products such as knives and drill bits.

During cladding welding of hardfacing wear-resistant steel plate, 30MnB5 tensile strength ksi, preheating and slow cooling should not be adopted. Sometimes, forced cooling measures are even taken to reduce the residence time of weld in the temperature range of 400-850℃ to prevent local chromium deficiency in austenite grain boundary and σ brittle phase in the plate, resulting in 475℃ brittleness, so as to ensure that the weld metal has good mechanical properties and intergranular corrosion resistance.

EN 10025-2 is standard for hot rolled products of structural steels. EN 10025-2 steel grades are 30MnB5 tensile strength ksi, S235JR, S235J0, S235J2 (S235 series); S275JR, S275J0, S275J2 (S275 series); S355JR, S355J0, S355J2, S355K2 (S355 series); and S450J0. The numbers 235, 275, 355, 450 indicates the min. yield strength for thickness ≤16mm. For example, when the thickness ≤16mm, the min. yield strength for S235 series steel is 235Mpa, S275 series steel is 275Mpa, S355 series steel is 355Mpa, and S450J0 steel is 450Mpa.

Our company has its own steel plate manufacturing plant, processing plant and steel pipe plant. We can machine the steel according to the 30MnB5 tensile strength ksi customer's requirements and meet the customer's requirements.
