What is Q390D carbon steel plate sheet equivalent ASME material

BEBON cpompany practice new development concepts, expand in an all-round way, deepen reform and innovation, speed up transformation and upgrading, become stronger, better and bigger, accelerate the implementation of BEBON Steel's Q390D carbon steel plate sheet industrial planning, and realize the revitalization and development of enterprises.Fully implement the corporate Q390D carbon steel plate sheet market dominant position, comprehensively promote contractual management, and promote the transition from "internal production" to "market operation”.

ASTM A335 P11, P22, P91 pipes are commonly used in power plants and chemical-petrochemical industry, while P9 and P5 pipes are mainly used in petroleum refineries. BBN steel company supplies ASTM A335 Cr-Mo alloy steel seamless pipes sized from 1/2″ to 24″ranging in wall thickness from SCH20 to XXS or even thicker. The Q390D carbon steel plate sheet specification covers nominal wall and minimum wall chrome-molybdenum( also known as Cr-Mo, or Cr-Moly) alloy steel pipe intended for high-temperature application.

The Q390D carbon steel plate sheet processing performance is good. Due to the uniform control of steel plate performance, excellent performance coordination and good toughness guarantee, the steel plate bending processing, drilling, cutting and other mechanical processing properties are excellent. In addition, the surface of the Q390D carbon steel plate sheet steel plate is smooth and beautiful by inhibiting and removing oxide scale from slab heating to rolling process and heat treatment in furnace without oxidation atmosphere.

The final heat treatment of quenched and tempered alloy steel, Q390D carbon steel plate sheet is quenching and high temperature tempering. The hardenability of quenched and tempered alloy steel is high, and oil is generally used. When the hardenability is very high, it can even be air cooled, which can reduce the defects of heat treatment. The final properties of quenched and tempered alloy steel depend on tempering temperature. Generally, it is tempered at 500 ℃ - 650 ℃. The required properties can be obtained by selecting tempering temperature. In order to prevent the second kind of temper brittleness, fast cooling (water cooling or oil cooling) after tempering is beneficial to the improvement of toughness.

ST37-2 is a kind of low carbon steel with carbon content of 0.20%, similar to S235JR or Q235 Q390D carbon steel plate sheet. It's not as strong as common ASTM A36, but it is also widely applied by everyday uses and structural applications where high strength is not so important. Equal ST37-2 angle steel size: Q390D carbon steel plate sheet Size: 20 × 20 mm to 200 × 200 mm. Thickness: 3 - 35 mm. Length: 6 m, 9 m or as required. Unequal ST37-2 angle steel size: Q390D carbon steel plate sheet Size: 30 × 20 mm to 250 × 90 mm. Thickness: 3 to 10 mm. Length: 6 m, 9 m, 12 m or per your request.
