At the same time, the company operates a variety of products of related iron and quenched and tempered GL-E40 hull steel plate steel enterprises. Annual sales of steel 3.6 million tons, standing stock of 400000 tons, has developed more than 10000 users. The company has a first-class marketing service system, strong storage and transportation capacity and supporting supply, cutting distribution capacity, and gradually build it into an important marketing channel. The company has obtained quenched and tempered GL-E40 hull steel plate ISO9001:2000 quality system certification, A-level credit unit of the people's Bank of China, and is an excellent supplier of many large state-owned enterprises.
The company's headquarters has a well-established logistics distribution system, which can quickly transport the steel materials to the port through the contracted logistics companies. Professional contracted logistics companies can significantly reduce costs and various commodity-related expenses. Meanwhile, the flexible transfer ensures that the quenched and tempered GL-E40 hull steel plate steel materials can be shipped immediately after passing the quality inspection.
Tempering the important quenched and tempered GL-E40 hull steel plate welding structure often use high temperature tempering to remove residual weld stress. Classification: high temperature tempering above 400 ℃, medium temperature tempering 250 ~ 400 ℃, low temperature tempering 150 ~ 250 ℃, Quenching +Tempering is improve quenched and tempered GL-E40 hull steel plate strength, plasticity and toughness.
In December, 2018, our Vietnam customer purchased 352 tons SA387Gr12Cl2 and SA387Gr11Cl2 quenched and tempered GL-E40 hull steel plate steel plates for their tank fabrication project. The customer need those cargo urgently, and we keep many stock in warehouse , it only takes about 3days we collect total cargo for shipping to customer. The customer are very appreciate our quality and service. They quenched and tempered GL-E40 hull steel plate become our regular customer and repeat order to us every month.
