Hydrogen Sulfide – NACE MR0175/ISO 15156 & NACE MR0103

Hydrogen Sulfide -MR0175/ISO 15156 & MR0103 NACE International has developed two significant standards relative to the use of materials in hydrogen sulfide-bearing environments. MR0175/ISO 15156, Petroleum and Natural Gas Industries – Materials for use in H2S-containing Environments in Oil and Gas Production; and MR0103, Materials Resistant to Sulfide Stress Cracking in Corrosive Petroleum Refining Environments.

Confused About Annealing and Heat Treating Terminology?

Confused About Annealing and Heat Treating Terminology? In the broadest sense, annealing is the process of heating an alloy to an elevated temperature to promote homogenous chemistry, equiaxed microstructure, and uniform mechanical properties to produce what is essentially stress-free, or “soft” material. In the stainless steel, nickel, and titanium alloy industries, the terms anneal, solution […]
How Stainless Steel Rusts

How Stainless Steel Rusts All grades of stainless steel contain a minimum of 10.5% chromium within their chemical composition which allows for them to form a continuous protective oxide layer along their surface. This oxide layer is what makes stainless steel resistant to rusting and other forms of corrosion. Although stainless steel has this protective […]

Stop Corrosion Before It Starts

Stop Corrosion Before It Starts Corrosion can occur when an alloy is exposed to moisture and other elements or chemicals which cause the material to deteriorate. Rolled Alloys has put together a list of tips to help you avoid corrosion. Choose Stainless Steel: Although all metals can corrode, stainless steels are more resistant to corrosion […]
