S690QL equivalent ASTM size list data

Manufacturing method of 12Cr1MoVR alloy: This plate is melted in oxygen top blown converter, open hearth furnace or electric furnace. After negotiation with the demander, other equivalent methods can also be adopted. S690QL equivalent ASTM, 12Cr1MoVR alloy steel plate is usually delivered in normalized + tempered state. According to the special agreement at the time of ordering, 12Cr1MoVR steel plate can also be delivered in Annealed or tempered state.

BEBON cpompany practice new development concepts, expand in an all-round way, deepen reform and innovation, speed up transformation and upgrading, become stronger, better and bigger, accelerate the implementation of BEBON Steel's S690QL equivalent ASTM industrial planning, and realize the revitalization and development of enterprises.Fully implement the corporate S690QL equivalent ASTM market dominant position, comprehensively promote contractual management, and promote the transition from "internal production" to "market operation”.

The advantage of hot-rolled stainless steel plate is that it can eliminate the damage caused by S690QL equivalent ASTM metal structure in the process of ingot casting to a certain extent, eliminate some tiny defects in the structure, refine the grains of stainless steel material, promote the structure of steel closer, and improve the performance of the material as a whole. This kind of lifting is mainly manifested in the rolling direction, which can make the S690QL equivalent ASTM steel no longer isotropic to some extent, and some defects such as bubbles, cracks and looseness formed during pouring can be eliminated under high temperature or high pressure.

The effect of elements in S690QL equivalent ASTM, wear-resistant steel plate on high-temperature temper embrittlement can be divided into: (1) Impurity elements such as phosphorus, tin, antimony and so on that cause the high-temperature temper brittleness of the wear-resistant steel plate. (2) Alloy elements that promote or slow down the brittleness of high temperature tempering in different forms and degrees. Chromium, manganese, nickel, silicon, etc. play a promoting role, while molybdenum, tungsten, titanium, etc. play a retarding role. Carbon also plays a catalytic role.
