Influence of the safety of a sustainable stainless steel
The Masa Stork Company recognized in the hydrocarbons sector in Colombia, in a power generation project saw the need to use 2-inch tubing to transport wastewater in the cooling of motor-generators, presenting the problem of fracture in the welding when they are put into operation. When stainless ste...
