The iron oxide defects on the surface of weather resistant S355J0W steel

The company has five major departments: steel plate production department (including quality inspection team), sales department, market development department, after-sales and logistics department, and finance department. The backbone of steel business from all over the country, with the chairman as the core, integrates self-confidence, independence, passion and responsibility, and strives for excellence! All people share the same belief: "Being a refined steel product line rewards customers, strengthen the steel industry, and realize the corporate dream!

A medium tensile, low carbon manganese steel S355JR is readily weldable and possess good impact resistance. This material is commonly supplied in the untreated or normalized condition. Structural unalloyed steel weather resistant S355J0W steel has a wide range of applications in construction, metallurgy, heavy and transport engineering, machine tool, power engineering and bridge building industries. Various profiles and metal structures, parts and elements of ground and underground equipment are made from steel S355JR.

Since the welding process is often used in the fabrication and processing of steel structures, it is very important for low-alloy high-strength steels of such purpose to be welded using the arc welding process that is widely used in thin thickness plates and steel strips. Yes, the welding seam of the steel structure should have the required strength and toughness, so as to withstand the most unfavorable conditions for the intended use. At present, the development of weather resistant S355J0W steel, low-alloy high-strength steels is carried out simultaneously with the development of various welding processes. Most low-alloy high-strength steels can be welded well.

The proportion of main elements in Q345 steel is basically the same as that in 16Mn steel, the difference is that V, Ti, Nb microalloy elements are added. A small amount of V, Ti, Nb alloy elements can refine the grains, greatly improve the toughness of the steel, and greatly improve the comprehensive mechanical properties of the steel. Because of this, the thickness of weather resistant S355J0W steel, Q345 steel plate can be made larger. Therefore, the comprehensive mechanical properties of Q345 steel should be better than that of 16Mn steel, especially its low temperature properties. The allowable stress of Q345 steel is slightly higher than that of 16Mn steel.

Our company doesn't need the cheapest quotation to choose international logistics company, but the price performance ratio will be high, the service will be good, and the transportation must be safe and punctual, which will not affect the time when the weather resistant S355J0W steel goods arrive at the destination, and the logistics situation will be well communicated with customers in advance. Therefore, when we choose international logistics companies, we will have a look at their timeliness and service attitude in advance. It is only important to transport goods according to the requirements of customers for logistics.

Expect in the weather resistant S355J0W steel goods regardless quality be still on the price after-sales service we all will keep in the middle of go together of advantage position real attain the ream customer satisfaction.Our advantage is: experienced craftsmen weather resistant S355J0W steel product development technology, excellent production team, hand strict quality control, sales and after-sales service.
