Marine class steel S690 steel

S690 steel, High-strength steel plates are widely used in many industries such as construction, automobiles, ships, machinery and equipment, but high-strength steel plates must be selected appropriately. First, the grade is too high, which means that the price will be high because of the high manufacturing cost. Second, the low level means that the safety performance cannot meet the standard. Third, we must strictly follow the design drawings to select high-strength steel plates specifications. Fourth, it is advised the purchaser to test the high-strength steel plates with special equipment.

We are world class steel S690 steel materials supplier. We are engaed in providing raw steel materials such as steel plates / steel coils / steel sheets / steel pipes, deep processing and a series project design and solutions to clients. We guarantee to return goods for free for S690 steel quality problem during its lifetime. Your satisfactory is our permanent pursue. We always welcome advise from clients to make self-improvement continously. And sincerely to build long-term cooperation with you.

Forging method is to use forging hammer, precision forging machine, fast forging machine or hydraulic press to forge ingot into steel, billet or forging blank. Forging is the earliest S690 steel processing method. Forging is divided into free forging and model forging. Forging method can obtain the finished steel with better mechanical properties and shapes that are not easy or impossible to obtain S690 steel by rolling method.

The effect of alloy elements on the properties of heat treatment methods for thick steel plate: the performance of heat treatment method reflects the difficulty coefficient level of heat treatment process and the tendency of defects caused by heat treatment process. The key points include cutting performance, over temperature sensitivity, quenching aging tendency and air oxidation carburizing tendency. S690 steel, Carbon steel has high machinability, and slow cooling method can be used in heat treatment, which can reduce the deformation and cracking tendency of the products. The addition of Mn and Si will increase the over temperature sensitivity of steel.
