Company name: Henan Lu Yun Trading Co. Ltd. contact: Yu is mobile phone number: 15639797063 Qinghai temperature hydrogen proof steel delivery state of cryogenic vessel.
15CrMoR steel plate won the "metallurgical product quality quality gold cup award", and passed the national exemption product certification.
First, Wugang 15CrMoR steel plate has the following advantages: XG08
1 pure steel: Wugang can produce P (0.010%), S (0.005%), N (70ppm), O (15ppm), H (2ppm), the total amount of inclusions in steel 20ppm high purity steel.
2 good toughness and weldability. XG08
3 leading heat treatment technology: normalizing, quenching, Hui fire, quenching and tempering and other heat treatment processes can be carried out according to the requirements.
4 significantly improve the plasticity and impact toughness of steel, and improve the anisotropy of steel.
Two. Basic information:
15CrMoR is a low alloy high strength steel, a steel belongs to their temperature.
"15" is a carbon content component of 0.15%;
"Cr" is a component containing a certain chemical element chromium;
"Mo" is a component containing a certain chemical element molybdenum;
"R" is the first letter of the container's container;
Delivery status: normalizing and tempering (normalizing temperature: 860 -760 -920, tempering temperature: 620 C / C), including impact at room temperature, high temperature tensile, bending stretch, etc..
Implementation criteria: GB713 / ASME / EN / WYJ/XG08
At 550 degrees below, it has a higher rupture strength.
Origin: Wugang, Wuhan, Chongqing, Nangang, Xingang, xiangtan.
