Smelting process of , container plate SPA-H weather-resistant steel: The molten iron for smelting SPA-H steel must be pretreated by molten iron desulfurization Before entering the converter, the sulfur content of the molten iron is ≤0010%, and the slag on the surface of the molten iron is cleaned Nickel plates, copper particles or nickel-copper alloys are added to the converter with scrap steel The carbon content of the converter smelting end is required to be less than 006% to prevent the molten steel from being oxidized,A709 grade 50W high strength steel.
42CrMo steel plate is an ultra-high strength steel plate, which is widely used in machinery manufacturing steel. The steel is suitable for manufacturing large and medium-sized plastic molds that require certain strength and toughness. 42CrMo steel has high strength and toughness, good hardenability, no obvious temper brittleness, high fatigue limit and multiple impact resistance after quenching and tempering, and good low temperature impact toughness.
A709 grade 50W high strength steel,Titanium microalloying is an element of strengthening complex with carbon and nitrogen. The addition of micro amount of titanium in the steel can fix almost all nitrogen and part carbon in the steel, so as to eliminate the strain aging phenomenon and improve the aging impact performance of the steel. At the same time, it can refine the grains and change the morphology of the compounds. According to the atomic weight ratio of Ti and N in tin formula (Ti = 3.4n), the content of Ti in steel should be controlled between 0.015 and 0.025%. Generally, the amount of ferrotitanium added to each ton of steel is 1kg.A709 grade 50W high strength steel
A709 grade 50W high strength steel,Q690D steel is a high-strength welded structural steel grade. Q the first letter of the Chinese spelling of Qu for the yield strength of steel; 690 represents the yield strength value, the unit is MPa, and D represents the grade of the steel plate; -20 ; common steel plate quality grade steel plates are Q690A, Q690B, Q690C, Q690D, Q690E.A709 grade 50W high strength steel
