Sunny Xinrui has a strong history spanning almost 16 years. Starting with big ideas in a relatively unknown corner of a small China city in 2001, we have risen to become one of the fastest growing special steel companies in China. We don't produce steels directly, but we can provide any special steel that hard to find in market, besides, you can get much lower price than directly from steel mills with same service of steel mills. We are the best bridge between customers and steel mills. Except steel making , we can provide all steel further processing in our factory. Including many ways of cutting(laser cutting, fire cutting, plasma cutting, saw cutting and water cutting), welding, bending, coating, cold drawn(pipes and round bars), machining and heat treatment. It's not a problem to get right steels for your project any longer in our company. In current commerce, time means money, with thorough processing and transporting systerm, you can get your products in amazing short time. If you relived about your order, no problem, you can pay balance after getting products in your stock. So what we do , just want to benefit customers and make business easier and happier.

Corten Steel Plate Atmospheric Corrosion Resistant Plates CORTEN A plates are produced from billet castings from blast furnace and hot rolled in a continuous mill for smaller thicknesses and on a four high mill for others. The purity of the steel of fine grade austenitic quality and the addition of special alloys, provide this steel plates, excellent mechanical characteristics, even at high temperatures and self-passivating properties when exposed to corrosive agents present in urban atmosphere. This property allows this steel to face down corrosion for longer periods when compared to common steel, even if not painted. Chemical Analysis % C Mn Si P S Ni V Cr Cu Max - 0.25 0.07 - - - - 0.3 0.25 Min 0.12 0.5 0.75 0.15 0.05 0.65 - 1.25 0.55 Applications The mechanical characteristics and the resistance to atmospheric corrosion make this steel, the best product for the fabrication of agricultural vans and railway wagons, structures of bridges, water pipes, fans, chimneys and boilers. Hot Forming This operation may be normally carried out in a temperature range of 800 °C to 1050 °C. If it is required to use a different temperature, it is advisable to carry out a normalizing treatment at the end. Welding COR-TEN A plates can be easily welded using all common procedures used for mild steel plates (spot,TIG, MIG, MAG, electrode etc.). It is however advisable to avoid tempering in the heated zone and therefore to limit the ratio of linear energy to the thickness. Considering the chemical analysis, it can be stated that COR-TEN A steel is not subject to cold cracking. Welded structures fabricated with COR-TEN A steel does not normally need thermal stress relief treatment. Please contact Sunny Xinrui Steel Group for the choice of electrodes. Flame Cutting This operation can be normally carried out with the usual methods. In general no preheat is required, but operation on plates with a temperature of less than 10 °C shall be avoided. Cold Bending CORTEN A is suitable for very strict bending operations. It is recommended to comply with the parameters given in the following table: Size Range Thickness:0.8-160mm Width: ≤4300mm Length: as requirement
