30CrMo Alloy Steel Plate Used In The Construction Of Pressure Vessels

Product Specification

Description

30CrMo steel plates are often used in the construction of pressure vessels, boilers, and heat exchangers, where high strength and resistance to elevated temperatures are required. They can also find applications in the oil and gas industry, automotive components, and structural engineering.

These plates are typically produced through hot rolling or controlled rolling processes and can be further heat-treated to enhance their mechanical properties. The specific properties of 30CrMo alloy steel plates, such as yield strength, tensile strength, hardness, and impact toughness, can vary depending on the manufacturing and heat treatment conditions.

About 30CrMo alloy steel

30CrMo is a type of alloy steel that is commonly used in the manufacture of steel plates. It belongs to the Cr-Mo (chromium-molybdenum) family of steels and is known for its excellent strength, toughness, and high-temperature resistance. The numerical designation "30" represents approximately 0.30% carbon content, while "CrMo" indicates the presence of chromium and molybdenum as alloying elements.

30CrMo alloy steel has high strength and toughness, high hardenability. Its critical hardenability diameter in oil is 15-70 mm. 30CrMo alloy steel also has good thermal strength and enough high temperature strength below 500℃. But its strength decreases significantly at 550℃. When alloy elements are at the lower limit, 30CrMo alloy steel has good weldability. But when alloy elements are near the upper limit, 30CrMo alloy steel only has medium weldability and needs to be preheated to more than 175℃ before welding. 30CrMo alloy steel has good machinability and moderate plasticity during cold deformation. 30CrMo alloy steel has the first kind of tempering brittleness in the range of 300～350℃ during heat treatment, and tends to form white spots.

30CrMo alloy steel is usually used in quenched and tempered state. When the carbon content of the steel is at lower limit, 30CrMo alloy steel can also be used as a high strength carburized steel at the center. In medium-sized machinery manufacturing industry, 30CrMo alloy steel is mainly used to manufacture quenched and tempered parts with large cross-section and working under high stress conditions, such as shafts, spindles, operating wheels, bolts, double-head bolts, gears and so on under high load; in chemical industry, 30CrMo alloy steel is used to manufacture welding parts, sheets and pipes, and welded structures.

30CrMo alloy steel plate is widely used in various large-sized mirror plastic mould, precision plastic mould, like: cars accessies, home appliances, electronic equipment plastic mould and so on.
