Steel strip is a branch of steel plate. Steel strip is a kind of narrow and long steel plate, also known as strip steel, produced by various steel rolling enterprises to meet the needs of different industrial departments and industrial production of various metal or mechanical products. The width of steel strip is within 1300mm, and the length is slightly different according to the size of each roll. Generally, steel strip is supplied in coils, with the advantages of high dimensional accuracy, good surface quality, easy processing and material saving. The steel strip is a kind of steel with large output, wide use and many varieties.
Weather resistant SPA-C steel,As the boiler steel plate is working under medium temperature (below 350 ℃) and high pressure, the boiler steel plate is not only subjected to high pressure, but also subjected to impact, fatigue load and water and gas corrosion. The performance requirements for boiler steel mainly include good welding and cold bending performance, certain high temperature strength, alkali corrosion resistance, oxidation resistance, etc.weather resistant SPA-C steel
No. 45 steel is commonly used medium carbon quenched and tempered structural steel. The cold plasticity of No. 45 steel is generally better than Annealing and normalizing are better than quenching and tempering No 45 steel has higher strength and better machinability than Q345 steel After proper heat treatment, it can obtain certain toughness, plasticity and wear resistance No 45 steel is suitable for hydrogen welding and argon arc welding, but not suitable for gas welding Preheating is required before welding, and stress relief annealing shall be conducted after welding,weather resistant SPA-C steel.
Weather resistant SPA-C steel,A36 is American Standard ASTM material, SS400 is Japanese Standard JIS g3101 steel material for general structure, Q235 is Chinese standard GB700 material. The limitation of the content of the Mn element differs depending on the thickness of the A36 steel plate, and the A36 steel plate of 20 mm or less does not contain Mn. The Q235 steel plate has requirements for the contents of C, Si, Mn, S, P and other elements. But SS400 steel plate only requires S and P to be less than 0.050, and no other element requirements.weather resistant SPA-C steel
