Alloy spring steel is a kind of steel which can improve the mechanical properties, hardenability and other properties of the steel by adding some alloy on the basis of carbon steel to meet the requirements of manufacturing various springs. Its advantages are that it integrates other materials, making spring more stable, durable, long life. material S690QL, Alloy spring steel has high elastic limit, high yield ratio, high fatigue strength and enough toughness.

Weathering steel generally adopts the process route of fine material into the furnace-smelting (converter, electric furnace-microalloying treatment-argon blowing-LF refining-low superheat continuous casting (feeding rare earth wire)-controlled rolling and cooling. The scrap steel is added into the furnace together with the charge, and smelted according to the conventional process. After the material S690QL steel is tapped, deoxidizers and alloys are added. After the molten steel is treated with argon blowing, the molten steel is cast. By adding rare earth elements to the steel, the material S690QL weathering steel is purified and the content of inclusions is greatly reduced.

We have our own factory, including the production and manufacturing of steel pipes, with a special material S690QL steel pipe manufacturer and storage warehouse. Welcome to visit our factory, we will provide customers with high quality products that meet the requirements. And has the perfect material S690QL after-sale service guarantee system, lets the customer save the worry and the labor.
