The market demand for en S690QL steel is increasing

Q355NHD is a weather-resistant structural steel used in construction, bridges, and railway vehicles. Q represents yield strength, NH represents weather resistance, and D represents quality grade (A, B, C, D, E) composition. en S690QL steel steel is an atmospheric corrosion-resistant steel plate with the properties of high-quality steel such as strength, ductility, forming, welding, abrasion, high temperature and fatigue resistance.

30CrMnSiA steel delivery status: en S690QL steel, 30CrMnSiA steel shall be delivered in the state of heat treatment (normalizing, annealing or high temperature tempering) or without heat treatment, and the delivery status shall be indicated in the contract. 30CrMnSiA steel has high strength, but it belongs to medium carbon quenched and tempered steel, with large hardenability, so its weldability is very poor. After quenching and tempering, 30CrMnSiA steel has high strength, enough toughness and good hardenability. And can be used as grinding wheel shaft, gear and sprocket.

TMCP process is an indispensable technology for our production of low alloy high strength wide and en S690QL steel thick steel plates. TMCP process can produce steel with high strength and toughness without adding too many alloy elements and complex subsequent heat treatment. TMCP is a process that can save alloy en S690QL steel and energy and is beneficial to environmental protection. A lot of our shipbuilding steel plates are produced by TMCP process.

From the order to the delivery, there are three quality inspections to ensure that the qualified rate of finished products is more than 100%. We promise that every order will be tracked in a timely manner to ensure that customers can receive goods safely and constantly listen to their opinions and suggestions, reflect on our own problems, and let customers feel at ease. We have a large warehouse in Shanghai and Tianjin, which can provide customers with sufficient sources of supply.
