Stainless Steel 420 Bolts

Stainless steel 420 bolts are appreciated for their high hardness of not less than 55 RC, admirable corrosion resistance and acceptable serviceability. These bolts are ideal for applications with high tensile strength and durability, where the bolts are expected to deliver the best performance, such as surgery tools, cutting tools, and moulds.

Chemical Composition of Stainless Steel 420 Bolts

The composition of Stainless steel 420 bolts is crucial for understanding their properties and performance in various industrial applications.

Thus, this table provides valuable insights into the chemical composition of these flanges, highlighting their properties and suitability. 

Mechanical Properties of Stainless Steel 420 Bolts

The table provides essential information for engineers and manufacturers to assess the integrity and durability of Stainless steel 420 bolts in demanding environments.

Thus, this valuable data on the strength, flexibility, and resilience of Stainless steel 316 bolts is crucial for ensuring reliability and longevity.

Advantages of Stainless steel 420 bolts

These are flexible bolts which offer numerous benefits for various industrial applications, which are as follows:

• High Hardness: The first positive feature of stainless steel 420 bolts is their useful hardness in resisting wear and tear in abrasive conditions.
• Good Mechanical Properties: Stainless steel 420 bolts have moderate mechanical properties, ensuring good strength and toughness when on load.
• Corrosion Resistance: Compared to the other stainless steel grades, this one does not have high levels of corrosion resistance, but for industries that need somewhat higher corrosion resistance, the stainless steel 420 is sufficient for use.
• Machinability: It can be easily machined by turning or by cutting in an annealed state, and it is not very tough. Heat treatments may be needed to recover mechanical properties after or in the middle of the machining process.
• Cost-Effectiveness: Stainless steel 420 bolts are less expensive than stainless steel 304 or 316 and other high alloy stainless steels, but they are more useful where very high corrosion resistance is unnecessary.

Stainless steel 420 bolts offer several advantages that make them suitable for industrial and commercial applications.

Common Applications of Stainless Steel 420 Bolts

Due to their excellent features, Stainless Steel 420 bolts are preferred in various industrial applications. Some of the main applications include.

• Cutlery and Surgical Instruments: The 420 stainless steel bolts are used in knife making, scissors and surgical implements where high hardness, corrosion, and sharpness features are desirable.
• Industrial Applications: It is applied to manufacturing equipment such as pumps, valves, and fittings with moderate corrosion strength and high hardness.
• Tooling and Tool Handles: Stainless steel 420 is applied for tooling uses where wear strength, as well as the level of hardness, plays a vital role, for instance, for moulds, dies, and tool handles.
• Textile Industry: Textile machinery parts are subjected to friction and wear of the bolts made from the stainless steel 420.
• Agricultural Equipment: These are used where they are needed for their strength, and they do not have to be subjected to heavy corrosion as is used in the following applications of the automotive industry: Agricultural machinery components.
• Firearms: Stainless steel 420 is used in barrels and certain interior parts that demand high awkwardness and corrosion opposition.

Stainless steel 420 bolts have applications across various industries due to their valuable features, which make them versatile.
