How to improve the hardenability of S420N carbon steel plate sheet

Based on the principle of win-win and mutual benefit, the company operates in good faith, strictly controls the quality, and provides perfect after-sales service, which has won unanimous praise. The success of the company is not only the S420N carbon steel plate sheet hard work and wisdom of the company's employees, but also the deep love of the majority of consumers. It also inspires all employees of the company to have the courage to strive. We will continue to innovate and leap forward, create greater brilliance of the enterprise, and make our own contribution to the development of the S420N carbon steel plate sheet steel industry.

Delivery status: Hot-rolled S420N carbon steel plate sheet steel In the hot-rolled state or controlled rolling state or heat treatment, the state of delivery, cold-rolled steel to the annealing state of delivery.

Grades S420N carbon steel plate sheet, Q345 (16Mn) and Q390 steel have good comprehensive mechanical properties, good welding performance, cold and hot workability and corrosion resistance. C, D, E grade steel has good low temperature toughness. Mainly used for ships, boilers, pressure vessels, petroleum storage tanks, bridges, power station equipment, lifting and transportation machinery and other higher-load welding structural parts.

Vanadium mainly exists in the form of carbide in S420N carbon steel plate sheet and so on steel. Its main function is to refine the structure and grain size of steel and reduce the strength and toughness of steel. When the solid solution is dissolved at high temperature, the hardenability is increased; conversely, if it is in the form of carbide, the hardenability is reduced. Vanadium increases the tempering stability of quenched steel and produces secondary hardening effect. The vanadium content in steel, except high speed tool steel, is generally less than 0.5%.

As for Q460 series low alloy steel, there are three quality Grade C, D, E. S420N carbon steel plate sheet, Q460C steel plates are mainly used in various large-scale engineering structures and light-weight structures that require high strength and large load. Q460C steel mechanical properties: Q460C yield strength MPa in different thickness: ≤16mm: ≥460; 16-40mm: ≥440; 40-63mm: ≥420; 63-80mm: ≥400; 80-100mm: ≥400; 100-150mm: ≥380. The tensile strength MPa: 550-720.Elongation: ≥17%.Impact test: 0 ℃ impact test: ≥34J.
