DC52D+ZF steel is a hot-dip galvanized steel sheet and coil. It is mainly used for appliances are featured with strong coating adhesiveness, high erosion-resistance, accurately controlled zinc coating thickness, high size precision, flat profile and good mechanical, processing and welding performance. Product JIS G 3114 grade SMA400BW weldability can be used for making outside and inside plates for home appliances.

Shipbuilding steel plates have always been the key products of our company, and it is sold well in many countries and regions around the world. The thinnest certifiable thickness of our shipbuilding steel plates is up to 3mm. We cooperate with classification societies to certify the shipbuilding steel JIS G 3114 grade SMA400BW weldability and issue EN10204 3.2 material test certificate. According to the certificate number, the customer can verify the source of the shipbuilding steel plates with the corresponding classification society near them.

Phosphorus is a very harmful element in JIS G 3114 grade SMA400BW weldability steel. With the increase of phosphorus content, the strength, flexion ratio and hardness of JIS G 3114 grade SMA400BW weldability steel increased, but the plasticity and toughness decreased significantly. In particular, the lower the temperature, the greater the impact on plasticity and toughness, increase the cold brittleness of steel.

JIS G 3114 grade SMA400BW weldability, 15CrMo alloy steel is Chinese material. It is characterized by high Chrome and Molybdenum contents. The 15CrMo alloy steel chrome content is 0.80-1.10, and molybdenum content is 0.40-0.55. Besides, 15CrMo carbon content is 0.12-0.18, silicon content is 0.17-0.37, manganese content is 0.40-0.70. The heating temperatures for quenching and tempering of 15CrMo alloy steel are 900 and 650 centigrade respectively. The yield point of 15CrMo alloy steel is 295Mpa.
