Composition and properties of 12MnNiVR steel plate

Introduction to 12MnNiVR steel plate:
12MnNiVR steel plate is a type of pressure vessel steel plate, and because it uses a quenched and tempered heat treatment process, it can also be called a quenched and tempered container steel plate. After quenching and tempering heat treatment, the strength and impact toughness of 12MnNiVR steel plate can be partially improved.

Chemical composition of 12MnNiVR steel plate:
There are many types of chemical components in steel plates, but each one has its own role. For example, carbon determines the corrosion resistance of steel plates, while silicon determines the yield and tensile strength of steel plates. Therefore, each one has its own relative role. And because the chemical elements of steel plates are not quantitative, only their maximum and minimum values can be specified, so detailed explanations are provided for the five elements of carbon, silicon, manganese, sulfur, and phosphorus.
12MnNiVR steel plate → (C) carbon element → ≤ 0.085;
12MnNiVR steel plate → (Si) silicon element → ≤ 0.300;
12MnNiVR steel plate → (Mn) manganese element → ≤ 1.500;
12MnNiVR steel plate → (P) phosphorus element → ≤ 0.015;
12MnNiVR steel plate → (S) sulfur element → ≤ 0.005;

Mechanical properties of 12MnNiVR steel plate:
12MnNiVR steel plate → yield strength → 540MPa;
12MnNiVR steel plate → elongation → 25%

Executive standard for 12MnNiVR steel plate:
The 12MnNiVR steel plate belongs to the national standard grade and follows the national standard GB/T19879.

Delivery status of 12MnNiVR steel plate:
The 12MnNiVR steel plate is delivered in a quenched and tempered heat treatment state. If there are other technical requirements, they can be declared in advance and reflected in the contract.

Application field of 12MnNiVR steel plate:
12MnNiVR steel plate can be used for manufacturing oil storage tanks, pressure vessels, etc.
