Stock S690QL material equivalent specification

S35C steel is a high-quality carbon structural steel, which has good plasticity and appropriate strength, good process performance, and acceptable welding performance. It is mostly used in normalized and quenched and tempered states. Grades included in the JIS G 4051 standard: S10C, S15C, S20C, S25C, S30C, S33C, S35C, S40C, S690QL material equivalent, S45C, S48C, S50C, S53C, S55C, S58C, S09CK, S15CK, S20CK.

In recent years, in line with the development trend of iron and S690QL material equivalent steel industry at home and abroad, we have accelerated the transformation of development mode, promoted structural adjustment, and formed a rich product series of medium and thick plates, hot rolled steel coils, profiles, steel pipes, etc., which S690QL material equivalent are widely used in automobiles, long-span bridges, railways, machinery, ocean and so on fields. Meanwhile, we also provide deep processing for the steel materials.

Superior process production line advantage sdf: The company has focused on weathering steel S690QL material equivalent, pressure vessel plate, oil tank plate, pipeline steel plates, and steel welded structures for many years, and has a strong factory scale; one of the domestic excellent weathering steel manufacturers, serving customers all over the world; using frequency conversion and microcomputer program control, the equipment is highly automated; Improve product efficiency and improve product quality.

Composition characteristics of Q420 alloy steel plate: 1.Low carbon: Due to the high requirements for toughness, weldability and cold forming performance, its carbon content does not exceed 0.20%. 2. Add manganese-based alloy elements. 3. Add auxiliary elements such as niobium, titanium or vanadium, which is beneficial to obtain fine ferrite grains and improve the strength and toughness of the Q420 alloy steel, S690QL material equivalent.

First of all, we should establish a correct concept of after-sales service. Service concept is an important part of corporate culture and a long-term enterprise value concept. Our company's after-sales service embodies the concept of "customer first, sincere service for customers". As long as we are in the "sincere service for users" under the guidance of the idea, I believe we will get rich returns.
