hardness of S690QL standard pdf

Scope of application of JIS G3101hardness of S690QL : SS400 steel plates and other steel products are suitable for general structural buildings, bridges and ships, and the final products are hot rolled products.

The mechanical properties of 30CrMo steel are as follows: tensile strength 930 MPa, yield strength 785 MPa, elongation after fracture 12%, impact absorption energy 63 J. hardness of S690QL, 30CrMo steel has high strength and toughness. When the temperature is lower than 500℃, 30CrMo steel has good high-temperature strength, good machinability, medium cold bending plasticity, high hardenability and good welding performance. 30CrMo steel is generally used in quenched and tempered condition.

Medium and thick steel plates are widely used in construction engineering, machinery manufacturing, container manufacturing, shipbuilding, bridge construction and so on. However, each project has different requirements for plate size. How to cut hardness of S690QL, medium and thick steel plates? There are many ways, for example, flame cutting, laser cutting, wire cutting, plasma cutting, ultra-high pressure water cutting and so on.

Our company has been established for 20 years and has accumulated rich experience in steel products. At the same time, it is often exported to Southeast Asia, Africa, South America and other countries. So you can rest assured that our hardness of S690QL products and our prices are very favorable. Because we have our own factory, there is no other cost, we can also carry out machining and so on.

With a high-quality and complete after-sales service system, the company solves the user's hindrance and improves the reliability of steel hardness of S690QL product quality. Reaching every corner of the globe with professional services, users anywhere can get thoughtful and detailed services form us is our pursue.
