What is the price of S690QL high tensile steel, spring steel? First, how much a ton of spring steel costs depends on the grade of spring steel, because different grades have different properties and prices. Second, it is also related to the market. The demand for S690QL high tensile steel spring steel is different every day, and the price of S690QL high tensile steel, spring steel is also changing every day. We can learn the current price of S690QL high tensile steel, spring steel through the network and steel market information. Third, how much a ton of spring steel costs depends on the manufacturers. Different manufacturers have different manufacturing quality and prices. Generally, the price of large factories is higher, but the quality is better guaranteed.

20# steel is carbon steel with carbon content of about 0.20%. It belongs to low carbon steel with high quality. The equivalent material of 20# steel is S20C. 20# steel has low strength and hardness, good plasticity and toughness, good carburizing effect and good weldability. 20# steel is often used to make pressure parts (such as gasket, chain piece), carburizing parts (gear, CAM), welding parts, plastic mold, etc.

Corrosion resistance mechanism of S690QL high tensile steel, stainless steel: obvious Cr2O3 film is formed on the surface of stainless steel, and the minimum content of O and Cr (10.5%) is required to obtain continuous protective film to prevent corrosion. If the protective film is damaged, it can recover naturally.

SPA-C steel with the thickness range is 1.2-150mm, the width range is 1220-4200mm, and the length range is 5000-18000mm. Also note that the S690QL high tensile steel, SPA-C steel coil thickness should not exceed 25 mm. SPA-C steel’s mechanical properties is yield strength more than 325 MPa, tensile strength more than 450Mpa.
