What is the RINA FH40 high tensile steel plate element chemical composition

In recent years, in line with the development trend of iron and RINA FH40 high tensile steel plate steel industry at home and abroad, we have accelerated the transformation of development mode, promoted structural adjustment, and formed a rich product series of medium and thick plates, hot rolled steel coils, profiles, steel pipes, etc., which RINA FH40 high tensile steel plate are widely used in automobiles, long-span bridges, railways, machinery, ocean and so on fields. Meanwhile, we also provide deep processing for the steel materials.

ABS class shipbuilding steel plate contains two kinds as common strength and high strength ship plate according to different yield and tensile strength.Common strength shipbuilding plates Grade A, B, D, E and F are mainly used to contribute hull of ship,and high strength shipbuilding plate are mainly built the cranes of bulk and breaker ships in low temperature surroundings. ABS Grade AH36, DH36, RINA FH40 high tensile steel plate, and EH36 plate rolling specifications range:Thickness within 3-300mm,Width within 1250-4000mm.

The elongation of low alloy high strength steel is 15% - 23%, and the impact absorption energy is more than 34J at room temperature. The RINA FH40 high tensile steel plate, low alloy high strength steel has good plasticity and impact resistance, which can avoid brittle fracture during impact, and make cold bending and welding easy. In addition, the brittle transition temperature of low alloy high strength steel is low, and the absorbed work value of Grade E steel is not less than 27J at - 40℃. This is of great significance to the engineering components and transportation tools such as vehicles, ships, offshore oil platforms, containers, bridges and so on.

Generally speaking, rolled plates are easier to handle in a high temperature environment, and the heat treatment of RINA FH40 high tensile steel plate, rolled plates is also very common. Hot rolling can not only greatly reduce energy consumption and save costs, but also improve the processing performance of metals and alloys, that is, the coarse grains in the as-cast state are broken, the cracks are healed significantly, and the processing performance of the alloy is improved.

Composition of low alloy steel plate: Low carbon: due to the high requirements for toughness, weldability and cold formability of low alloy steel plate, the carbon content is not more than 0.20%; manganese is added; the auxiliary elements such as niobium, titanium or vanadium are added; a small amount of niobium, titanium or vanadium forms fine carbide or carbonitride in the steel, which is conducive to obtaining fine ferrite grains and improving the strength and toughness of low alloy steel plate; in addition, The corrosion resistance of RINA FH40 high tensile steel plate, low alloy steel plate can be improved by adding a small amount of copper (< 0.4%) and phosphorus (about 0.1%).

The company always adheres to the quality policy of "Quality First, Continuous Improvement, Customer Satisfaction" and the business philosophy of "Continuous Progress, Pursuing Excellence", as always, we look forward to cooperating with you to create a new situation for common development.Steel products RINA FH40 high tensile steel plate price concessions, rich industry experience, complete varieties.
