Product Description
13-8 MO Introduction
13-8 MO 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.
13-8 MO Chemical Composition
13-8 MO 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 Socket Weld Cross
Introduction to common type of Socket Weld Cross
Socket welding cross is a pipe fitting that combines the characteristics of socket connection and welding. This pipe fitting is usually composed of a spigot, a socket, a bent part and a socket slot, etc., characterized in that there is a socket slot on the spigot, and the spigot and the socket are respectively located at both ends of the bent part. Socket welding cross joints are usually used to change the direction of the pipeline and are an important part of the pipeline system. In addition, the socket welding cross joint can be applied to different materials and industrial standards, and has the advantages of simple structure, beautiful shape, quick disassembly and assembly, flexible operation, low fluid resistance, and safe and reliable use. These characteristics make the socket welding cross widely used in industrial fields such as dairy, food, beer, beverage, pharmaceutical, and cosmetics

Product processing
1. Material Selection & Preparation: Raw materials like steel bars (UNS S13800) are cut into appropriate lengths based on the required size.
2. Forging: The metal is heated and forged into a cross shape, creating a robust, high-strength blank. Forged fittings are generally superior for high-pressure applications.
3. Heat Treatment: To relieve internal stress and improve physical properties, the forged cross undergoes heat treatment, including quenching and tempering.
4. Machining and Socketing: The blank is machined according to ASME B16.11 standards to create the specific socket dimensions,which include the socket bore (B), bottom bore (D), and wall thickness.
5. Thread Cutting (If Applicable): While this request focuses on welding, some socket crosses may be threaded, although socket welding relies on fillet welding rather than threads.
6. Surface Treatment: The finished cross is cleaned, deburred, and treated (e.g., rust-proof coating, sandblasting) to protect against corrosion.
7. Inspection and Testing: A rigorous check is performed, inspecting dimensions (center-to-bottom) and checking for cracks. Typical tolerances for 1/2" to 3/4" are ±1.5mm, and up to ±2.5mm for 2.5" to 4".
