Shipbuilding steel plates are used to manufacture the hull of marine and inland ships. High strength, plasticity, toughness, cold bending performance, welding performance and corrosion resistance are required for shipbuilding steel plates. Boiler steel plates are used to manufacture various boilers and important accessories. As the boiler steel plate works under medium temperature (below 350℃) and high pressure, it is also subject to impact, fatigue load and water and gas corrosion. The Corten A sheets spot, boiler steel plate is required to ensure a certain strength and have good welding and cold bending properties.
Tempering includes high temperature tempering, medium temperature tempering and low temperature tempering. Tempering means to reheat the Corten A sheets spot quenched steel to a certain temperature and then cool it in a certain way. Tempering can reduce or eliminate the internal stress produced by quenching, reduce the hardness and strength, and improve the ductility or toughness of steel. After Corten A sheets spot quenching, the workpiece should be tempered in time, and the required mechanical properties can be obtained through the combination of quenching and tempering.
The Indonesia INKA is the only train carriage maker for railway industry in Indonesia. We cooperated with them since 2012 and supply them SPA-H steel. The SPA-H steel is used by them to fabricate train carriage. We have huge stocks for SPA-H steel and can arrange delivery for them in short time after receiving order. Meanwhile, our product Corten A sheets spot quality has passed their test for so many times use. Therefore, they trust us and give us repeat orders regularly. And we also do our best to support them and have never let them down though past cooperations.
