Identification method of fake API 5L PSL2 X42 seamless steel pipe As we all know there are lots of steel suppliers in the world, but not all of them produce the high quality API 5L PSL2 X42 seamless steel pipe . Katalor has the rich experience in API 5L PSL2 X42 seamless steel pipe. And next we will tell you how to find the fake API 5L PSL2 X42 seamless steel pipe. 1. Easy to present the fold. The occurrence of folding is a variety of fold lines formed by the appearance of  API 5L PSL2 X42 seamless steel pipe , which usually runs through the longitudinal direction of the pipe. Folding occurs because the counterfeit manufacturers seek high efficiency, the amount of pressing is too large, and the ear is generated. When the next rolling occurs, the folding occurs, and the folded API 5L PSL2 X42 seamless steel pipe is cracked after being bent, and the strength of API 5L PSL2 X42 seamless steel pipe is greatly reduced. 2. The appearance often has the appearance of pockma

General technical requirements of API 5L PSL1 X42 steel pipe For API 5L PSL1 X42  steel  pipe, Katalor include different size to meet customers' requirements. Katalor as the famous API 5L PSL1 X42 steel pipe supplier in China, we export our steel products to all over the world. And the API 5L PSL1 X42 steel pipe is also very popular among our customers. API 5L PSL1 X42 steel pipe is a low-carbon or ultra-low-carbon microalloyed steel. It is a high-tech and high value-added product. API 5L PSL1 X42 steel pipe has following general technical requirements:  (1) High strength. The strength indicators of API 5L PSL1 X42 steel pipe mainly include tensile strength and yield strength. At the same time, high strength is required, and the yield ratio (ratio of yield strength to tensile strength) of pipeline steel is also required.  (2) High impact toughness. Pipeline steel requires that the material have a sufficiently high impact toughness (fracture, fracture toughness).

Elemental Ni has the significant role in JIS G4304 SUS 420J1 steel plate JIS G4304 SUS 420J1 steel plate has certain wear resistance and corrosion resistance, high hardness. JIS G4304 SUS 420J1 steel plate price is the lower class of stainless steel ball. Instruments, transportation tools, household appliances, etc. JIS G4304 SUS 420J1 steel plate is used in the manufacture of parts resistant to atmospheric, steam, water and oxidizing acid corrosion. The addition of element Ni and the increase of Ni content lead to the increase of thermodynamic stability of SUS420J1 alloy, so SUS420J1 alloy has better properties of rust and oxidation resistant medium. With the increase of Ni content, the performance of the reductive medium of SUS420J1 alloy is further improved. It is worth pointing out that nickel is the only important element to improve the stress corrosion of many medium of SUS420J1 alloy.  Nickel also improves the high temperature oxidation resistance of SU
