Overview

Grade 416 steel is a free-machining stainless steel with a machinability of 85%, the highest of all stainless steel. With most of the free-machining stainless steels, adding sulfur can improve the machinability, leading to manganese sulfide inclusions. The addition of sulfur also reduces the formability, weldability, and corrosion resistance of 416 steel to below that of grade 410. Because of their high machinability and low cost, grade 416 steel is available in highly tempered, hardened, or unhardened forms.

Application

The superior machinability and corrosion resistance of stainless steel grade 416 makes it ideal for various industries. It’s often used in the automotive and aerospace industry as well as medical and food processing equipment, valves, pumps, fasteners, and marine hardware.

Physical Properties

The physical properties of SS416 also contribute to its overall performance. This steel has a 7.74 g/cm3 density and a melting point of 1450° C. It is excellent at conducting heat but has less conductivity for electricity than other metals, such as copper or aluminium.

Mechanical Properties Stainless Steel 416

Grade 416 Stainless Steel Corrosion Resistance

Due to its high chromium content, Grade 416 offers good corrosion resistance in many environments, including mild acid solutions like vinegar or citric acid solutions, without any significant pitting or crevice corrosion issues, unlike some other ferritic grades such as 409, which can suffer from this issue if exposed to these conditions over extended periods.

SS416 Heat Resistance

AISI 416 has good oxidation resistance up to around 800˚C but should not be exposed to temperatures above 870˚C due to the risk of embrittlement or loss of strength at these temperatures.

Package Process

1.with plastic cap to protect both ends

2.weaving bag wrapped outside the pipe

3.then pack into wooden case.
