At the same time of doing well in A514 Gr E structural steel material production and operation, Yunnan company focused on completing the four phases of technical transformation construction projects, realizing industrial upgrading, improving equipment level, and laying a good foundation for the future development of the company. In the A514 Gr E structural steel material technological transformation project, pollution control facilities have been built synchronously, and a large number of comprehensive utilization projects, such as comprehensive sewage treatment and recycling project, blast furnace gas waste heat and residual pressure power generation, have been invested and constructed.
Under normal exposure to the atmosphere, A514 Gr E structural steel material, bare steel forms a tight protective oxide film during the first few months of atmospheric corrosion. Sometimes architects choose bare steel structures because they want to get the appearance of uniform atmospheric oxidation on the steel surface, and sometimes they are to save the protective coating for economic purposes. To use these low-alloy high-strength steels in a bare state, the design must consider that the surface of the steel cannot be wet for a long time, and special attention should be paid to the special atmospheric environment to ensure that the corrosion rate of the steel is allowed under this condition.
Manganese steel plates emerge as a profitable solution to diverse kinds of acid attacks. These have qualities surpassing an ordinary steel plate. Neither fully austenitic nor ferritic, these plates A514 Gr E structural steel material provide boosted resistance to chloride stress corrosion cracking, which the 300 series stainless steel plates are susceptible to. 22% Chromium allows these plates to withstand Sulphuric and Hydrochloric acid attacks, whereas Molybdenum (up to 3%) avoids crevice and pitting corrosion.
WTST 37-3 steel plate is a kind of carbon steel plate. WTST 37-3 steel plate can be used to build low temperature sea water resistant containers. When the customer orders A514 Gr E structural steel material WTST 37-3 steel plate from us, our factory should roll it in full accordance with SEW 087-2 specification, and the factory will issue the original mill test certificate for inspection before delivery.
A514 Gr E structural steel material, S355JR is a European standard low alloy high strength structural steel, which is in accordance with EN10025-2. The hardness of S355JR steel is 70-80B, and the yield strength of S355JR steel is 355MPa. JR stands for quality level, equivalent to level B in ChinaChemical composition of S355JR steel: C: < 0.22; Si: < 0.55; Mn: < 1.60; P: < 0.025; S: < 0.025S355JR steel is equivalent to Q345B in China.
