Molybdenum effect Molybdenum in pure γ-Fe in the maximum solubility of about 3%, ω (C) ≈ 0.25% ~ 0.30%, the maximum solubility in austenite is about 8%. Molybdenum in pure α-Fe the maximum solubility of about 32%, and decreased with temperature can precipitate...

Chromium on the corrosion resistance of stainless steel decisive role in the definition of stainless steel, ω (Cr) ≥ 10.5%, which is the main element of stainless steel, corrosion resistance, the higher the chromium, corrosion resistance higher possible....

Chromium in stainless steel performance decision has become the main element, the fundamental reason is to add chromium steel as an alloying element, the internal contradictions of its campaign in favor of resistance to the development of corrosion damage....

Selection of stainless steel and nickel alloys , the first element is choose the correct stainless steel and nickel alloy grades. Stainless steel and nickel alloy that contains many of the standard level, between the level of chemical composition , corrosion...

Hardness testing of seamless stainless steel pipes need to take into account its mechanical properties, performance and quality of this is related to the deformation of stainless steel as raw materials, stamping, cutting and other processing. Therefore,...

Barlow's formula can be used to estimate burst pressure of steel pipes or tubes. P = 2 s t / (do SF) where P = max. working pressure (psig) s = material strength (psi) t = wall thickness (in) do = outside diameter (in) SF = safety factor (in general 1.5...

A power plant engineer has many choices when selecting steel tubing materials for his condenser, feedwater heater or balance-of-plant application. The wide variety of stainless steel choices available (ASTM lists over 75 alloys) gives the engineer greater...

Tubes Heat exchangers with shell diameters of 10 inches to more than 100 are typically manufactured to industry standards. Commonly, 0.625 to 1.5" tubing used in exchangers is made from low carbon steel, Admiralty, copper, copper-nickel, stainless steel,...

Pressure Rating for standard seamless stainless steel pipes , temperature from 100oF to 750oF. All ratings in psig based on ANSI/ASME B31.1.The operating (allowable) internal pressure of a vessel, tank, or piping used to hold or transport liquids or gases.The...

Stainless steel Tubing and hose can be thought of as a cylindrical thin-walled pressure vessel. The strength of thin walled pressure vessels is determined by: 1. The material strength 2. The wall thickness, and 3. The size of the tubing. The formula is:...
