Different types of stainless steel have different mechanical properties. Martensitic stainless steel has high strength and hardness, which is suitable for manufacturing parts with corrosion resistance, high strength and high wear resistance, such as turbine shaft, stainless steel cutter, stainless steel bearing, etc. TMCP CCS EH32 engineering ships steel, Ferrite stainless steel has moderate mechanical properties and low strength. However, it is resistant to oxidation and is suitable for various industrial furnace parts.
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 TMCP CCS EH32 engineering ships steel 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.
S355J2 steel plate rolling process is controlled rolling process. In the rolling process, the ingot rolling temperature is 1000-1050℃; in the first stage, the low-speed and large reduction rolling process is adopted, the high-temperature stage is 950-1000℃, the TMCP CCS EH32 engineering ships steel rolling speed is 1.6-2.0m/s, the single reduction rate is 15-20%, and the cumulative reduction rate is 40-45%, so as to ensure sufficient deformation of ingot. In the first stage, the start rolling temperature is 910-930℃, and the finish rolling temperature is ≤ 870℃.As a basic building material, steel plates are currently widely used in automobiles, shipbuilding, chemical industry, aerospace and other fields. Reasonable selection of flaw detection methods to ensure the quality of TMCP CCS EH32 engineering ships steel steel plates is of great significance to safe production. Common defects of steel plates are folding, inclusion, shrinkage, air bubbles, delamination and cracks. These problems can be discovered in time through flaw detection.
Since its establishment, the company has participated in several key railway and highway projects. After years of development, the company’s TMCP CCS EH32 engineering ships steel domestic market has been exported to more than a dozen provinces and cities including Kunming, Shenzhen, Hunan, Sichuan, Shanghai, Nanjing, Heihe, Jilin, Inner Mongolia, and Xinjiang . International trade is exported to Kazakhstan, South Korea, Vietnam, South Africa and many other countries, and has been well received by customers.
Our company will accept the product quality objection registration record, pass it to the TMCP CCS EH32 engineering ships steel production unit and relevant departments, and timely coordinate the supervision of product TMCP CCS EH32 engineering ships steel quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
