Tensile strength is the maximum amount of tensile stress a material can withstand before it fails or breaks. It is a measure of the material's ability to resist deformation under tension or stretching forces.When high tensile loads are applied, ductile and brittle materials will approach...
18/8 stainless steel is the most widely used and flexible austenitic form of stainless steel. The numbers 18/8 represent the composition of this steel; it is 18% chromium and 8% nickel, making it very resistant to corrosion and oxidation.18/8 stainless steel is also highly durable and easy to...
Absorption is a chemical or physical phenomenon in which the molecules, atoms and ions of the substance getting absorbed enters into the bulk phase (gas, liquid or solid) of the material in which it is taken up. Absorption is the condition in which something gets mixed or absorbed completely in...
The United States has a significant natural gas transportation and storage network. While companies are exploring transporting hydrogen using existing assets, careful consideration needs to be given to hydrogen's unique properties, and how they may impact pipeline assets.
It is essential to understand the advantages and disadvantages of each metal coating type to select the one that is best for your application.
