In terms of service, our service is a "one-stop" way of working. We have our own 100mm GL-A40 quenched and tempered steel processing plant and pretreatment plant, pretreatment of ship steel (shot blasting, derusting, painting). Technical parameters of steel plate and profile steel surface pretreatment production line. We can also let customers enjoy our other pretreatment services, such as 100mm GL-A40 quenched and tempered steel cutting, welding, drilling, galvanizing, etc., at the lowest cost.
In the whole steel structure and steel body, the medium and heavy plate is an important part, once the problem occurs, it is easy to fracture, collapse and occur explosion. So how to judge whether the medium and heavy plate, 100mm GL-A40 quenched and tempered steel is of high quality? First of all, check whether there are cracks on the surface of the 100mm GL-A40 quenched and tempered steel plate and how glossy it is. Secondly, to measure the thickness error of medium and heavy plate, it is better to use the instrument to measure the bending tensile value. Finally, observe the scale of the steel plate manufacturers, whether there are relevant qualification certificates, and how the production process is.
In November of 2015, Thailand one company contacted with us from Internet. They are find the trustable supplier of S355J2H seamless pipe 100mm GL-A40 quenched and tempered steel for there cable car supporter. Due to the special using of the pipes, they are very careful and servious when choosing the supplier. After one months contact and discussion by email, they come to our company. We drive to the pipe mill for visit of 2 days. Through this visit, they are very confident with our production ability and proucts quality. Finally, they accept the grade we suggest Q345D. After back to office, they put the order of 1400 tons pipe to us directly.
Good impact resistance. Wear resistant composite steel plate uses low carbon steel or low alloy, stainless steel and other toughness as the base material. The 100mm GL-A40 quenched and tempered steel metal material not only has good wear resistance, but also can withstand the impact and wear of falling from high to low in the transportation process. It has good heat resistance. Vanadium, molybdenum and other 100mm GL-A40 quenched and tempered steel alloy materials are added into the alloy wear-resistant layer during the manufacturing process, so it can be used and worn at high temperature ≤ 800 ℃. Compared with ordinary 100mm GL-A40 quenched and tempered steel carbon steel substrate, it can only be used below 380 ℃, while low alloy heat-resistant steel plate can work below 540 ℃. This shows how high the heat resistance coefficient of wear-resistant steel plate is. Good corrosion resistance.
We guarantee to provide all technical data required by users within one hour to provide reasonable quotation; to provide 100mm GL-A40 quenched and tempered steel reasonable quotation for products consulted by users within one hour; to provide investigation reception: we guarantee to receive the investigation of users at any time and provide various convenient conditions for users.
We are leading supplier of pipeline steel. The pipeline steel in usually in forms of pipeline steel coils, pipeline steel sheet, pipeline steel plate and pipeline steel pipes. And the most popular standard is API 5L. For questions about 100mm GL-A40 quenched and tempered steel pipeline steel, such as X70 steel properties, API 5L X42 steel properties, difference between API 5L PSL1 and API 5L PSL2, API 5L grade B steel price, please feel free to communicate with us.
