Q370qDNH steel plate atmospheric corrosion resistance steel grade: Q—The first letter of the Chinese pinyin of "qu" for the yield strength of steel used in bridges; 370-a specified value of small yield strength, unit MPa; q-the first letter of the Chinese pinyin of the word "bridge" for bridge steel; D—The quality level is D level; N——The first letter of the Chinese phonetic alphabet of the word "Nei"; H——The first letter of Pinyin of "hou"; Q370qDNH steel standard: GB/T 714-2015.

High wear resistance: fully automatic CNC stacking equipment, independent of manual B750L thermomechanically processed welding technology, produces fully qualified high-quality products. Special automatic welding technology enables the chromium content of wear-resistant layer to be controlled at more than 28%, and the B750L thermomechanically processed hardness is between 58-62, which fully ensures that our wear-resistant layer has continuous good and balanced wear resistance. The wear test in metallurgy, cement and other industries shows that the wear resistance of the wear-resistant layer of the surfacing composite B750L thermomechanically processed wear-resistant steel plate is more than 30 times that of the 16Mn plate with the same thickness.

In order to easily and economically perform hot or cold processing to make various parts of engineering structures, the low alloy high strength steel must have appropriate forming properties. Like B750L thermomechanically processed, carbon structural steel, low alloy high strength steel can generally be processed in such way, as well as cutting, punching, and machining. Although the yield point of low alloy high strength steel is high, even if the forming operation is deformed quite severely, cold bending presses, drawing machines, presses and other equipment used for carbon structural steel forming can also be used for low alloy high strength steel, but some equipment needs to be modified.

The gas cylinder steel is one of our featured products. The pickled LPG steel is available. We supply gas cylinder steel coil, gas cylinder steel sheet and gas cylinder B750L thermomechanically processed steel plates. Welcome to consult any question about gas cylinder steel or LPG steel, such as JIS G3116 SG295 coil price, SG255 material properties, SG325 plate dimensions, HP265 equivalent, P245NB steel properties, etc. We are always here to serve you.

First of all, we should establish a correct concept of after-sales service. Service concept is an important part of corporate culture and a long-term enterprise value concept. Our company's after-sales service embodies the concept of "customer first, sincere service for customers". As long as we are in the "sincere service for users" under the guidance of the idea, I believe we will get rich returns.
