Stainless steel grades 304, 304L, and 304H represent distinct variations used in crafting CNC components. Each grade possesses distinctive properties and features, rendering it suitable for diverse applications in CNC production.

The stainless steel grade UNS S30400 stands as the most extensively employed variant, acclaimed for its exceptional corrosion resistance and strength. This versatile grade finds application in various fields such as food processing equipment, kitchen appliances, and surgical instruments. Additionally, its robustness and durability make it a prevalent choice in crafting CNC components.

UNS S30403, a low-carbon iteration of 304, is recognized for its enhanced weldability and formability. This variant is frequently employed in manufacturing CNC components that necessitate welding or bending, such as pipes and tubing. Moreover, it finds application in the production of pressure vessels and boilers.

UNS S30403, characterized by elevated strength and hardness, represents a high-carbon adaptation of 304. This variant is widely employed in crafting CNC components demanding robust strength, such as valves and fittings. Additionally, it finds application in the manufacturing of heat exchangers and other high-temperature applications.

The three stainless steel grades, namely 304, 304L, and 304H, belong to the austenitic category, acclaimed for their exceptional corrosion resistance, strength, and durability. Notably non-magnetic and featuring a low coefficient of thermal expansion, these grades prove ideal for CNC components necessitating precise measurements and tight tolerances.

Regarding machinability, the three DIN grades 1.4301, 1.4306/1.4307, and 1.4301 exhibit ease of machining and can be processed using standard tooling. Additionally, they are readily polishable, allowing for a high level of shine and smoothness in the finishing process.

Stainless steel grades 304, 304L, and 304H find common usage in crafting CNC components, with each grade boasting distinctive properties suitable for varied applications. Stainless steel 304 excels in corrosion resistance and strength, 304L in improved weldability and formability, and 304H in heightened strength and hardness. Notably, all three grades share non-magnetic characteristics and a low coefficient of thermal expansion, rendering them well-suited for CNC components demanding precision in measurements and tight tolerances.
