The alloy elements in S690QL1 ASTM equivalent

Our 1810mm production line successfully rolled 1.2mm × 1250mm ultra-thin specifications S690QL1 ASTM equivalent high strength automotive steel, and the product quality and performance fully met the standards. In recent years, customers have become increasingly demanding for lightweight vehicles. Our company aims at the market and focuses on the development of thin-gauge high strength automotive S690QL1 ASTM equivalent steel. The research and development personnel adjusted the product composition based on theoretical calculations and drawing on other experiences to meet customers' higher requirements for automotive steel yield strength and tensile strength.

Customer service center has provided after-sales service for many large-scale information systems, and has accumulated rich working experience in the process of S690QL1 ASTM equivalent service for many years. It can provide accurate, timely and high-quality support and service for users, which is well received by users.

S355J2 is a European standard low alloy high strength structural steel grade, equivalent to Q345D. Because of its good impact toughness and welding performance, S355J2 steel plate is widely used in bridges, ships, power plant equipment, hoisting and transportation machinery, machinery manufacturing and other engineering and welding structures that bear high loads. S355J2 steel plate delivery status: hot rolled delivery, the S690QL1 ASTM equivalent specific delivery status should be indicated in the contract.

Hardness comparison between Q345B steel and NM450 steel: wear resistant steel for construction machinery requires high wear resistance, high toughness, impact resistance, easy welding, easy forming and other high-performance characteristics. The main index of wear resistance is the surface hardness. The higher the hardness, the better the wear resistance. Compared with S690QL1 ASTM equivalent, Q345B steel, the hardness of NM450 steel is only increased 3 times, but the average service life is increased 6-8 times under the same working conditions.

The Qatar Railways company launched a tender for designing ,construction and completion of Green Line Project. Our company has participated in the bidding from Qatar Railway Company since May, 2016. A delegation from project visited several famous S690QL1 ASTM equivalent pipe mill in China for 15 days in July,2016. Of course the delegations had visited our pipe mill.
