Product Description
13-8MO Introduction
13-8MO Introduction
Stainless steel grade 13-8 Mo has a high toughness and excellent resistance to stress corrosion cracking. It has been designed to handle applications where high strength, corrosion resistance, toughness, and stress resistance are essential. This is a martensitic alloy.
13-8MO Chemical Composition
13-8MO Chemical Composition
Grade 13-8 stainless steel is a high-strength, precipitation-hardening martensitic alloy known for superior toughness, corrosion resistance, and excellent transverse properties. It typically contains 12.25-13.25% Chromium, 7.5-8.5% Nickel, and 2.0-2.5% Molybdenum, often used in aerospace, nuclear, and petrochemical applications.
Introduction to common type of Butt Welding Olet
Introduction to common type of Butt Welding Olet
Butt welding olets (or buttweld fittings/outlets) are pipe fittings with beveled ends designed to be welded end-to-end with pipes, offering high strength, superior flow, and excellent leakage resistance. They are ideal for high-pressure, high-temperature, and hazardous fluid applications in industries like oil & gas, chemical processing, and power generation.it is stronger, suitable for high pressure/large diameters, requires skilled labor, superior fatigue resistance

Product processing
Butt welding olets (weldolets) are manufactured by hot or cold forming (forging) raw material—typically steel (UNS S13800)followed by machining to create a self-reinforced, beveled, 90-degree branch connection. They are designed for high-pressure applications, offering strength through specific, optimized shapes and are regulated by ASME B31.3 codes.
Production Process Steps:
* Raw Material Preparation: The process begins with special stainless steel (UNS S13800) .
* Forming/Forging: The material is heated and formed (hot or cold) using dies to create the contoured shape, which acts as a reinforced branch fitting.
* Machining: The forged piece is machined to exact dimensions. This includes creating the beveled end, which is essential for the butt-weld connection.
* Heat Treatment: To relieve residual stress and enhance mechanical properties (hardness/strength), the fitting undergoes heat treatment.
* Inspection and Finishing: The finished weldolets are subjected to inspections, including dimensional checks, material testing, and NDT (Non-Destructive Testing) before being coated or finished.
