China Supplier of SCM440H Alloy Structural Steel Bar
Shanghai Katalor is a Chinese Supplier of SCM440H Alloy Structural Steel Bar. We can offer SCM440H gear steel with large quantity. SCM440H gear steel is the production of high-strength fasteners commonly used steel. It has a stable composition, low harmful elements, high purity steel, and heat treatment quality and hardness uniformity. The decarburization layer is small, less surface defects, easy to use when the ball annealing, cold Upset cracking rate is low. Widely used in the engine, mold and other industries.
