Custom CNC Turning 304 Stainless Steel Shaft Lock

Production introduction: Manufactured by Yijin Hardware, a precision CNC turning parts manufacturer, this custom precision CNC turning shaft lock of stainless steel 304 is a dedicated part to the tray table of the passenger cabin chair in a civil airplane.

The 304 stainless steel is a common type of stainless steel with a density of 7.93 g/cm³ which is also called 18/8 stainless steel, implying that the content of chromium is over 18% and the content of nickel is over 8%.

Featuring 800℃ heat resistance, good machinability and high toughness, it is widely used in industry, furniture and decoration, as well as food and healthcare.

It needs to be noticed that food-grade 304 stainless steel has stricter content requirements than common 304 stainless steel.

For example, internationally 304 stainless steel is defined with a chromium content of 18 – 20% and a nickel content of 8 – 10%, but the food-grade 304 stainless steel contains 18% chromium and 8% nickel, with a certain tolerance and limited contents of various heavy metal elements. In other words, the 304 stainless steel is not necessarily food-grade 304 stainless steel.
