1/4 inch 25CrMo4 CE maximum BBN steel stock
Our company will set up a full-time service engineer for the project, who is responsible for the interface and coordination of technical support and after-sales service of the 25CrMo4 CE maximum project. In response process of customer service center, in case of technical support and after-sales service demand, the user shall contact the full-time engineer of 25CrMo4 CE maximum customer service center, and the technical personnel will give corresponding answers and on-site treatment according to the needs of users.
Boiler steel refers to the special steel used to manufacture pressure components of steam boilers, such as steam drums. The boiler steel mainly means boiler steel plates and seamless boiler steel pipes. Boiler components not only bear pressure loads but are also heated by direct fire, so the requirements on the chemical composition and mechanical properties of boiler steel, 25CrMo4 CE maximum are strict. In the chemical composition of boiler steel, 25CrMo4 CE maximum, sulfur and phosphorus are strictly controlled. Tensile strength, yield point, elongation, impact energy value and 180 ° cold bending are required to be tested in boiler steel mechanical properties. In addition, strain aging impact test is also required for boiler steel. The quality control of boiler steel is slightly higher than that of pressure vessel steel.
Tempering includes high temperature tempering, medium temperature tempering and low temperature tempering. Tempering means to reheat the 25CrMo4 CE maximum quenched steel to a certain temperature and then cool it in a certain way. Tempering can reduce or eliminate the internal stress produced by quenching, reduce the hardness and strength, and improve the ductility or toughness of steel. After 25CrMo4 CE maximum quenching, the workpiece should be tempered in time, and the required mechanical properties can be obtained through the combination of quenching and tempering.
In Nov, 2018, our Mozambique customer purchased from BBN company 500 tons carbon steel Q235B steel structure for building 10 units of gas station. We have been cooperate more than 5 years for providing plate and pipes and 25CrMo4 CE maximum profile as beginning, and they are very satisfied with all the received Cargo. We extend in-house cutting, welding, grinding, bending and certification and testing of our products, on client demand. If you are interested in our steel structures or steel plate price, welcome to contact us.
