Hot rolled St52-3 carbon steel plate sheet heat treatment

In the development process of more than 20 years, the company keeps pace with the times, keeps innovating its ideas, constantly adjusting its steel product St52-3 carbon steel plate sheet structure, constantly strengthening its comprehensive competitiveness, constantly improving its management level, and more importantly, forming its corporate culture of elements and personality. The company always strives to build itself a comprehensive competitive steel St52-3 carbon steel plate sheet supplier in the world.

ASTM A387 steel plate is suitable for temperature range (316-593). It's high temperature performance is still the focus of attention, even if the current trend is for applications with high CVN toughness requirements. ASTM A387 steel St52-3 carbon steel plate sheet tends to be fin-shaped, low-silicon, low-sulfur, calcium treatment, and occasionally produced Q&T to provide the highest level of toughness.

Compared with ordinary steel, the St52-3 carbon steel plate sheet special steel has the following characteristics. First, the special steel has better physical properties, higher strength, stronger compressive strength, and better precision. Second, the special steel has better chemical properties, such as high temperature resistance, low temperature resistance and corrosion resistance. Third, the composition of the special steel is more diversified, which can be synthesized by integrating other elements, such as alloy steel, high carbon steel, etc. Fourth, special steel is more flexible for processing.

The allowable working temperature of boiler steel plate is generally below 475 ℃, which can't meet the needs of high temperature working condition. Chromium molybdenum steel is one of the common steels for St52-3 carbon steel plate sheet pressure vessels, which is widely used in various hydrogenation units and reforming units in oil refining and chemical industry. Therefore, on the basis of common St52-3 carbon steel plate sheet carbon steel, alloy elements such as Cr Mo V are added, which has excellent hydrogen corrosion resistance and good high temperature strength, It is the material of high temperature and high pressure vessel shell and head.

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, St52-3 carbon steel plate sheet, etc.

The company focuses on two markets at home and abroad, and has a group of 56 experienced sales elites and professional and technical personnel. It can provide customers with drawing design, St52-3 carbon steel plate sheet deep processing services and installation solutions. 20 years of project experience has provided high-quality carbon steel, alloy steel products and high-quality after-sales service to customers in many countries around the world.
