Our company was founded in 2000, which initially committed to providing high-quality steel en10025 S460ML products for China's rapid infrastructure construction. With the advantages of steel resources and good reputation in the domestic market, combined with the huge demand for steel in the international market, we began to export en10025 S460ML steel to the international market, opening up the international steel market.

321 stainless steel has excellent high-temperature stress rupture performance and high-temperature creep resistance, stress mechanical properties, are better than 304 stainless steel. Austenitic stainless steel is equivalent to the Chinese grade 0Cr18Ni10Ti. 321 stainless steel is Ni-Cr-Mo austenitic stainless steel, its performance is better than 304. Due to the addition of titanium metal, en10025 S460ML, 321 stainless steel plate and sheet have better resistance to grain boundary corrosion and high temperature strength.

Compared with en10025 S460ML, pressure vessel and boiler steel plates have such advantages: The pressure vessel and boiler steel should be pure, and the fracture structure of the boiler steel plate should be uniform without cracks and inclusions. Besides, the strain aging sensitivity is small, and the strain aging impact value of the pressure vessel and boiler steel plate is required to be no less than 50% of the non-aging impact value. That is why pressure vessel and boiler steel plate is first choice for fabricating pressure vessels and boilers, while en10025 S460ML is not.

The yield rate is a comprehensive technical and economic index in the production of medium and heavy plates such as en10025 S460ML. Increasing the yield rate can not only reduce the loss of metal, but it is also vital to the economic benefits of the steel enterprise. The influencing factors of the yield of medium and heavy plates are various, for example, the variety structure, negative deviation rolling level, plate shape control level, cutting loss, rolling waste and burning loss, etc.

The yield strength of en10025 S460ML, Q235 steel plate decreases with the increase of thickness. Q235 steel plate thickness≤16mm, yield strength is 235MPA; 16mm < Q235 steel plate thickness≤40mm, yield strength is 225MPA; 40mm < Q235 steel plate thickness≤60mm, yield strength is 215MPA; 60mm < Q235 steel plate thickness≤100mm, yield strength is 205MPA; 100mm < Q235 steel plate thickness≤150mm, yield strength is 195MPA; 150mm < Q235 steel plate thickness≤200mm, yield strength is 185MPA.

our company is a professional ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates steel exporter and a steel Stockist in china. We keep more than en10025 S460ML 1000 tons ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates steel in stock every month.

After the order is finished, our after-sales service center will send an email to make a feedback about our steel products' quality. We have phone service every three months to remind our customers of the possible problems and collect advices or suggestions in quality and service. Upon the collection of advices or suggestions, our after-sales service will quickly make technical solutions to wipe out the customer problem.
