How to distinguish the fake API 5L PSL1 Gr.B seamless steel pipe

 
As we all know, the market of API 5L PSL1 Gr.B seamless steel pipe is very large. So there are many fake API 5L PSL1 Gr.B seamless steel pipe in the steel market. Katalro will introduce how to judge the fake API 5L PSL1 Gr.B seamless steel pipe.

1. Susceptible to crusting. Two reasons, one is that the seamless raw material of the API 5L PSL1 Gr.B seamless steel pipe is uneven, and there are many impurities; the second is that the guide equipment of the fake and inferior manufacturers is simple, and these impurities are prone to scarring after rolling. 

2. Easy to present the fold. The occurrence of folding is a variety of fold lines formed by the appearance of API 5L PSL1 Gr.B seamless steel pipe, which usually runs through the longitudinal direction of the API 5L PSL1 Gr.B seamless steel 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 PSL1 Gr.B seamless steel pipe is cracked after being bent, and the strength of API 5L PSL1 Gr.B seamless steel pipe is greatly reduced.

3. Easy to scratch. The equipment of the fake and inferior manufacturers is rudimentary, and it is prone to burr scratching the appearance of the API 5L PSL1 Gr.B seamless steel pipe. The strength of the API 5L PSL1 Gr.B seamless steel pipe is lowered after the deep scratch. 

So if you want to buy the high quality API 5L PSL1 Gr.B seamless steel pipe, you should contact Katalor. You can purchase any sizes of API 5L PSL1 Gr.B with affordable price. And we can offer the more information about API 5L PSL1 Gr.B seamless steel pipe.

The Straightening of Corten B channel steel To straighten out the bend and shape of Corten B channel steel in rolling, cold, transport, etc., to make the shape correct and straight by straightening so that meet the Corten B channel steel  quality requirements. There are some reasons to impact the straighten of Corten B channel steel. Effect of straightening equipment on quality of  Corten B channel steel . Corten B channel steel straightening generally use 7-roll to 11-roll roller straightening machine. Small Corten B channel steel  using more rolls straightening machine; The roller straightening quality is good, and the roller straightening for large Corten B channel steel is complicated, so it is often used in seven-roll straightener. Effect of straightening technology on quality of Corten B channel steel . Because the Corten B channel steel is an asymmetrical rolled piece, the temperature is low in the thinner part of the...

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...
