RINA AH40 marine steel sheet cold brittleness

Wear resistant steel plate is a kind of special plate product specially used under the condition of large area wear. At present, the commonly RINA AH40 marine steel sheet used wear-resistant steel plate is a plate product made by overlaying a certain thickness of hard and wear-resistant alloy wear-resistant layer on the surface of ordinary low carbon steel or low alloy steel with good toughness and plasticity. The wear-resistant steel plate RINA AH40 marine steel sheet consists of two parts: carbon steel plate and alloy wear-resistant layer.

Low-alloy steel plates have low carbon content, and because ferrosilicon is not used for deoxidation, the silicon content in steel is often <0.07%. The outer layer of rimmed steel is crystallized in a rimmed state, so the surface layer is pure and dense, the surface quality is good, and the Zhengzhou low alloy steel plate RINA AH40 marine steel sheet has good processing performance. Rimmed steel does not have large concentrated shrinkage cavities, uses less deoxidizer, and the cost of steel is low.

keyword} product plate production process:
Raw materials (scrap steel, pig iron and molten iron) → electric furnace (100 tons electric arc furnace smelting) → converter → LF furnace molten steel refining treatment → VD or VOD furnace molten steel vacuum treatment → die casting (various key die casting lines) or continuous casting (large Slab caster) (50 tons of slab electroslag furnace for remelting a steel ingot) → heating (continuous furnace and soaking furnace) → steel plate rolling (4100 and 4200mm rolling mills) → steel plate heat treatment (normalizing and tempering) Quality) →Steel plate cutting inspection→Inspection

The company has sufficient stocks and complete specifications. The common carbon steel plates, marine plates, RINA AH40 marine steel sheet and storage tank steel plates sold are all produced by large state-owned steel companies such as Shougang, Hegang, Taiyuan Iron and Steel, with quality assurance and worry-free after-sales. The company develops and grows under the concept of seeking innovation in stability and advancing with the times for development. After a short period of development, it has begun to take shape.

Due to other non-steel quality reasons caused by the customer dissatisfaction, to timely explain to the customer, and help them solve the problem, for the customer really because of their own reasons, to give patient reply.The process of objection handling is the process of our technical service.
