Virami Steel Hub is a leading manufacturer, supplier, stockist, and exporter of high-performance Stainless Steel 13-8Mo Round Bars in Mumbai, India. We supply 13-8Mo round bars across India and export globally to the USA, Canada, Europe, Russia, Middle East, Australia, and Southeast Asia. Our materials are manufactured in accordance with international standards and undergo stringent quality testing to ensure superior mechanical strength, dimensional precision, and reliability in critical applications.
Stainless Steel 13-8Mo Round Bars are widely used in aerospace, defense, petrochemical, nuclear, and high-pressure industrial environments due to their exceptional strength, toughness, and corrosion resistance.
Stainless Steel 13-8Mo (UNS S13800) is a martensitic precipitation-hardening stainless steel. It offers high strength, excellent toughness, and good corrosion resistance. The alloy contains chromium and nickel for corrosion resistance, along with molybdenum to enhance strength and resistance to localized corrosion.
The designation “13-8Mo” refers to:
Unlike austenitic stainless steels, 13-8Mo achieves its high strength through precipitation hardening heat treatment, making it suitable for critical structural and load-bearing components.
Because of these characteristics, 13-8Mo is commonly used in aerospace structural parts and high-performance mechanical components.
Role of Alloying Elements
The low carbon content improves weldability and toughness.
Mechanical properties vary depending on heat treatment condition (H900, H1000, H1100, etc.).
Typical Mechanical Properties (H900 Condition):
Typical Mechanical Properties (H1100 Condition):
\The heat treatment process allows flexibility in achieving required strength-toughness balance.
One of the key advantages of 13-8Mo is its precipitation hardening capability.
Step 1: Solution Treatment
Step 2: Aging (Precipitation Hardening)
Reheated to specific temperatures such as:
This controlled aging process produces extremely high mechanical strength.
Stainless Steel 13-8Mo offers:
However, it is not as corrosion-resistant as austenitic grades like 316 in marine chloride environments.
It performs well in aerospace, defense, and structural industrial applications where strength is more critical than marine-level corrosion resistance.
Machinability is moderate in the solution-annealed condition and more difficult in hardened condition.
Machining Guidelines:
Stainless Steel 13-8Mo offers good weldability compared to other high-strength martensitic steels.
Proper procedure ensures maintenance of mechanical properties after welding.
