Is the hydraulic pipe joint stainless steel or carbon steel?
Of course, the corrosion resistance can not be done. But wear resistance, machinability is much better than stainless steel. See what parts of your connection are made of
Hydraulic pipe head for material 20, 45, 27SiMn and so on. The corrosion resistance of hydraulic pipe fittings is not stainless steel per se,
The strength of carbon steel is higher than that of ordinary stainless steel.If it's only for hydraulic lines, it's better for carbon steel, whether it's cost or pressure resistance.
