Q960 quenched and tempered steel grade classification: Q960C, Q960D, Q960E, Q960F. The product LR grade B hull steel plates thickness is not more than 150MM. Q960 quenched and tempered steel has high yield strength and tensile strength, and its resistance to brittle failure is also great. Q960 quenched and tempered steel has excellent low temperature toughness, so it can be used in large welded structural parts and low temperature environments.
A572 Grade 50 hot rolled plates and sheets are exhibiting features such as high tensile strength, oxidation and corrosion resistance, working ability, durability, long-lastingness, and formability. All these are responsible for making it the best selection. In addition to that these HR plates LR grade B hull steel plates maintain the properties for a longer duration at the high temperature with no harm. The documents are also offered by us to our clients like MTC as per EN10204/3.1b, radiography test report, packaging list, size and quantity inspection and so on to give surety that only premium quality of the product is supplied to them.
Normalizing is to heat the steel parts to 30~80℃above the critical temperature for a period of time. Then the parts are taken out of the furnace and cooled in air. Since the cooling rate of normalizing is faster than that of annealing, the strength and hardness of normalized LR grade B hull steel plates are higher than that of annealed LR grade B hull steel plates, but the elimination of internal stress is not as good as annealing. The normalizing operation of LR grade B hull steel plates is simple, the cost is low, the productivity is high, and it is widely used in actual production.
It is a modern high-tech professional enterprise integrating scientific research, LR grade B hull steel plates production and sales. The company is mainly engaged in the manufacture, installation and commissioning of boiler and pressure vessel, chemical, metallurgical, petroleum and other equipment, as well as LR grade B hull steel plates process technology development, technology transfer and related technical consulting and technical services.
Before delivering our hot rolled plate product we apply various tests to check the quality of carbon steel LR grade B hull steel plates plates such as- mechanical test, chemical test, hardness test, toughness test, eddy current test, impact test, micro test, flaring test, flattening test, etc. We are provided best packing for structural steel plates to avoid rust. Our after-sales service team will contact you if you have any question.
