How long will steel coil SPA H high quality last not rust outside?

Nowadays, transportation is an important factor in economic development. Our company's rapid development is also inseparable from a good geographical location. The company is located in Zhengzhou, an important steel coil SPA H high quality heavy industry area in Central China. Whether you are in Beijing, Shanghai or Guangzhou, you can visit our company very easily. My factory is nearby, convenient transportation and time saving.

If the wall thickness of the elbow is relatively thick, it is best to perform stress relief heat treatment on the weldment immediately after welding. This is especially true for large-thickness weldments Q235B, high-rigidity structural parts, and weldments that work under severe conditions (dynamic load or impact load). The tempering temperature for stress relief is 600～650℃. For thin-walled elbows, stress heat treatment is not necessary after welding.

DIN 17102 TStE355 is mainly used for grain structure steel and normal rolling steel. Tste355 steel plate is a kind of grain structure steel. It is a standard rolled steel plate / sheet specially manufactured for different types of welding structures. It is made of basic materials, with high temperature resistance and low temperature resistance. Product steel coil SPA H high quality is suitable for pressure boiler, mobile and vertical storage tank, high pressure pipeline, bridge, mast, cable, etc.

The basic principle of steel coil SPA H high quality, heat treatment of steel: put the metal workpiece in a certain medium and heat it to a suitable temperature, keep it in this temperature for a certain time, and then cool it at different speeds. Objective: to obtain the desired structure and properties by means of heating, heat preservation and cooling, so as to make the metal workpiece have the required mechanical, physical and chemical properties.

SPA-C steel with the thickness range is 1.2-150mm, the width range is 1220-4200mm, and the length range is 5000-18000mm. Also note that the steel coil SPA H high quality, SPA-C steel coil thickness should not exceed 25 mm. SPA-C steel’s mechanical properties is yield strength more than 325 MPa, tensile strength more than 450Mpa.
