Density 8 g/cm³ 0.290 lb/in³

AISI 316 is an austenitic stainless steel with added molybdenum, making it highly resistant to corrosion and suitable for demanding environments.

The addition of molybdenum enhances its resistance to pitting and crevice corrosion, especially in chloride-rich environments like seawater. It also improves its strength at high temperatures, making it ideal for use in chemical processing, marine, and industrial applications where durability and performance are crucial.

X5CrNiMo17-12-2 is widely used in high-corrosion and high-temperature applications. View the electrical resistivity of SUS 316 grade.

Due to its molybdenum content, SUS 316 offers excellent resistance to rust, chemicals, and extreme heat. This makes it suitable for use in harsh environments such as marine, chemical processing, and medical industries.

The electrical resistivity of SS 316 is around 7.2×10⁻⁵ ohm-cm, which is much higher than metals like copper and aluminum. This means it is a poor conductor of electricity and is often used in applications where electrical resistance is needed.

Forging of SUS 316

Forging Temperature Above 925°C
Alloy 316 has great creep strength, check the machinability of 316 Stainless Steel.

Its high creep strength allows it to maintain structural integrity under high temperature and pressure over long periods. This makes it ideal for use in industrial equipment, medical instruments, and offshore structures.

The machinability of SS 316 is rated at 60%, which means it is more challenging to machine compared to materials with a higher rating. It requires specialized tools and slower cutting speeds, which increases machining time and costs. However, its resistance to work hardening and high hardness make it a durable choice for precision parts.
