What is difference 34crmo4 steel for fastener and s235
The company always adheres to the 34crmo4 steel for fastener principle of "quality first, user first", and takes every cooperation seriously. It is our biggest wish that the steel material, specification and quantity can fully meet the requirements of users. With good reputation, high quality products and low price, we are willing to work together with old and new customers to create a great 34crmo4 steel for fastener cause. Customers are welcome to visit our company at any time. We are always ready to support you.
The steel plate used for containers and pressure vessel has to bear different pressures and strengths due to the manufactured containers. The normal pressure is generally 31.4MPa or higher; the working temperature is usually between -20 ℃ -450 ℃, and sometimes lower than -20 ℃. According to the working conditions and processing technology of the container, the 34crmo4 steel for fastener, steel plate used for the container must have good cold bending and welding performance. Besides, it should have good plasticity and toughness, high temperature short-term strength or long-term strength performance.
The excellent properties of wear resistant steel plate meet the strict requirements of high strength, high wear resistance, stability, straightness and surface quality. The combination of high hardness, high strength and excellent impact toughness makes 34crmo4 steel for fastener plate become an ideal material for a wide range of applications. The production thickness of wear resistant steel plate is generally between 8-100mm.
30CrMnSiA steel delivery status: 34crmo4 steel for fastener, 30CrMnSiA steel shall be delivered in the state of heat treatment (normalizing, annealing or high temperature tempering) or without heat treatment, and the delivery status shall be indicated in the contract. 30CrMnSiA steel has high strength, but it belongs to medium carbon quenched and tempered steel, with large hardenability, so its weldability is very poor. After quenching and tempering, 30CrMnSiA steel has high strength, enough toughness and good hardenability. And can be used as grinding wheel shaft, gear and sprocket.

Hot rolled plates are known for their superior mechanical properties over commodity grades of merchant bar. The hot rolled 34crmo4 steel for fastener plates products are made to specific chemistry and mechanical properties ranges, allowing them to be used in engineered applications. Resulting shafts, axles, and gears can be used in the automotive 34crmo4 steel for fastener industry and agriculture equipment. A36 mild steel has good strength, formability, and excellent welding properties. We also can supply welding, fabricating, and bending service.
The after-sale service of iron and steel products includes after-sale tracking service, technical guidance, transfer of relevant bills, handling of objections and many other contents. The handling of quality objections accounts for a large proportion. When dealing with these problems, we should distinguish the responsibilities, and compensate or return the inconvenience or loss caused to users due to steel.
