Thermal processing of EN 10025 S355ML steel plate steel sheet

According to the data released by the world iron and Steel Association, the world pig iron production in March 2020 was 103 million tons, a year-on-year decrease of 3.5%, a year-on-year increase of 1.8% in February, and the overseas pig iron EN 10025 S355ML steel plate production excluding China was 36.309 million tons, a year-on-year decrease of 11%. In March, except for China and Russia, pig iron production increased by 1%6, other countries' pig iron EN 10025 S355ML steel plate production decreased year-on-year, with 28 EU countries reducing by 14.2%, 3 CIS countries (Russia, Ukraine and Kazakhstan) reducing by 0.8%, India reducing by 14.6%, Japan reducing by 7.9% and South Korea reducing by 9.5%.

The company has the industry's advanced automated production lines and precision laboratory instruments and a capable steel industry management team. Through scientific management, optimized technology, and rigorous testing, the company will keep the production efficiency and production quality at the leading level in the industry and continue to provide customers with high-quality EN 10025 S355ML steel plate products. At the same time, the company is committed to building a comprehensive steel manufacturing industry and strives to make the company leads new progress and development.

40Cr steel plate is one of the most widely used steel in machinery manufacturing. After tempering, it has good comprehensive mechanical properties, good low temperature impact toughness and low notch sensitivity. The hardenability of steel EN 10025 S355ML steel plate is good. It can be hardened to Ф28 ～ 60mm during water quenching and Ф15～40mm during oil quenching. When the hardness is HB174～229, the relative cutting workability is 60%. The steel is suitable for making medium-sized plastic molds.

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 EN 10025 S355ML steel plate steel materials can be shipped immediately after passing the quality inspection.

With the increase of temperature, the yield limit of EN 10025 S355ML steel plate will decrease monotonically, but the tensile strength of EN 10025 S355ML steel plate will rise to a high peak value at a certain temperature, and then decrease. This peak temperature is called the blue brittleness temperature of EN 10025 S355ML steel plate. Near the blue brittleness temperature, the EN 10025 S355ML steel plate strength increases and the plasticity decreases. The elongation and section shrinkage of EN 10025 S355ML steel plate increase with the increase of temperature, but there is a low peak at the blue brittleness temperature. The blue brittleness temperature of low carbon steel ranges from 200 ℃ to 250 ℃. The blue brittleness of low alloy steel is not obvious as that of low carbon steel, and the blue brittleness temperature is higher.

The company has a high-quality management, technology and R&D team, and adopts independent research and development, domestic innovative process optimization combination. Relying on advanced manufacturing technology and sophisticated production testing equipment, it has ensured the high quality of products EN 10025 S355ML steel plate and won a good reputation. We can offer various kinds of steel materials in GB, ASME, ASTM, JIS, DIN, EN, API standards and specifications.

The company strengthens process management and pays attention to assessment. One of the key points of good service is to strengthen the process management and improve the evaluation mechanism. Make the after-sales service system more perfect and provide better service for customers.
