Whether S460M steel specification can be quenched to obtain martensite

The company is committed to providing customers with high-quality and low-cost S460M steel specification steel products as the goal, striving to create value for customers as its own responsibility. With advanced Kaiping processing equipment and strong logistics distribution system, the company can meet the needs of customers at any time. The company has the advantages of S460M steel specification complete specifications, low price and fast distribution, With the service concept of keeping promise and valuing quality, it has won the trust and unanimous praise of the majority of users. The scale and strength of the enterprise is in the forefront of domestic metal material business units.

After heating, a billet is refined for several passes of rolling, then edge cutting and straightening to become a S460M steel specification steel plate, which is called hot rolling. Due to its high strength, good toughness, easy processing, good weldability and other excellent properties, hot rolled steel plate products are widely used in shipbuilding, automobile, bridge, construction, machinery, pressure vessel and other manufacturing industries.

The steel plate for hull structure is also called marine plate or shipbuilding steel. Due to the harsh working environment of the ship, the hull shell is subject to the chemical corrosion of seawater, so the requirements for steel for the hull structure are strict. First of all, good toughness for marine plate S460M steel specificationis the most critical requirement. In addition, it requires higher strength, good corrosion resistance, welding performance, processing performance and surface quality.

S355J2 steel plate S460M steel specification 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 rolling speed is 1.6-2.0m/s, the S460M steel specification 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℃.

S460M steel specification, Grade P295GH chemical composition under EN10028-2:2003 is displayed as follows. Chemical composition (C: 0.08 to 0.20; Cr: ≤0.30; Si: ≤0.40; Cu: ≤0.30;Mn: 0.90 to 1.50; Mo: ≤0.08;P: ≤0.025; Nb: ≤0.020;S: ≤0.015; Ni: ≤0.30;Al: ≤0.020; Ti: 0.03; N: ≤0.012; Vi: ≤0.02). The yield Strength MPa (min) of P295GH steel plate with thickness less than 16mm is 295MPa, and the tensile strength is 460-580MPa.

After-sales service team is a key department to test the steel quality. Product quality is always the foundation of our survival and development. The company's full inspection from raw materials to finished products; and implements standardized, scientific, and strict internal quality control and management systems in accordance with the process flow during the production process; products can only leave the factory if qualified, and follow-up problem solving systems are implemented in after-sales services to guarantee the customers’ interest.
