**Seamless Honed steel tube for hydraulic steel cylinder ST52 50.8mm * SCH40**

Hydraulic seamless tube process:
The preparation process comprises the following steps: A. ingot through smelting, refining, vacuum degassing, continuous casting round billet process, made of B tube blank; and into the lubricating liquid for dipping pretreatment; C, the blank is a pre-treated hotline, hot piercing; D, on the tube billet hot rolling punching the water; e, the seamless tube cooling after quenching and tempering process. Through the above-mentioned method, the seamless steel tube for the hydraulic steel cylinder and the preparation process can improve the performance of the steel pipe, the manufacturing process is simple, and the service life is long.

seamless steel tube for hydraulic steel tube, steel ingot material comprises the following components: C:15-30 parts by mass, Si:2-8, Mn:6-15, Cr:3-10, Al:20-40, Ti:1-5, V:1-10, Zr:1-8, Ca,10-20, B:0.8-5.5: H:0.1-0.5, Pm:0.02-0.2 and Sm:0.05-0.5 for the rest, Fe:300-1200 and 0.1-0.3 impurities.

All our technology innovation is only for one aim--- the best quality, even that means a higher cost and lower production rate.
1. Checking raw material before producing.
2. Checking one by one before the assembling
3. Checking one by one during the production
4. Have a random inspection before the delivery.
