S890QL steel equivalent vs s355jr steel material

ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates are structural quality carbon steel plates just as S890QL steel equivalent. ASTM A573 steel gardes are in three tensile strength ranges intended primarily for structural applications at atmospheric temperatures for which improved toughness is required.

Our company is a large S890QL steel equivalent steel enterprise integrating steel plate production, sales and processing. It is a first-class agent of Shanxi Taigang, Shanghai Baosteel, Jiugang, Xi'an Huaxin, Taishan steel, Dongfang special S890QL steel equivalent steel and southwest special steel. It is a special dealer of famous steel plants in China, such as Columbus, NAS, acerinox, Outokumpu, Arcelor, nipponmetalindustry, nipponyakinkogyo, NSC, etc.

Cold rolled S890QL steel equivalent steel sheet can be produced by two high mill, four high reversing mill, multi high reversing mill and tandem cold mill. Although there are still only two work rolls in four high and multi high rolling mills, each work roll is supported by one or more large diameter backup rolls, which can prevent deflection of work roll. As a result, wide and thinner S890QL steel equivalent steel plates can be produced. For example, 20 high mill can produce as thin as 0. 001 mm sheet, but the two high mill can only produce as thin as 0. 35mm sheet

Molybdenum is a well known alloy element. Molybdenum can refine the grains of steel material, improve the hardenability and thermal strength, and maintain sufficient strength and creep resistance at high temperature. Adding molybdenum to S890QL steel equivalent, structural steel can improve mechanical properties. Molybdenum can also restrain the brittleness of alloy steel caused by quenching treatment.

The company has passed the ISO9001: 2008 quality system certification, strictly implemented the ISO9001 quality management system. Besides, we have continuously improved the after-sales service network to make every effort to provide more convenient, accurate and faster services for all customers. We will supervise the production, control the quality in the factory, Inspect the cargo before shipment, Issue the test report to sales department. From the steel prodcution to steel delivery, we always focus the whole process.
