440C Round Bar

Achieve optimal performance with 440C stainless steel round bar.

Strength and durability with 440C round bar.

Precision engineering meets superior quality with 440C round bar.

The high carbon content of 440C Stainless results in a material with exceptional hardness and strength. The existence of Carbon, the chromium content is sufficient to maintain the stainless characteristics of the material.

Machinability & Welding

440c bar stock is a high-carbon martensitic stainless steel that is known for its excellent strength, wear resistance, and corrosion resistance. It also has good machinability and weldability.

The machinability of 440C round bar is relatively good when compared to other high-carbon steels. However, it is important to note that the high hardness of the material can make machining difficult. Proper machining techniques and tools are necessary to achieve a high-quality finish.

440c stainless steel bar can also be welded using standard welding techniques such as gas tungsten arc welding (GTAW), gas metal arc welding (GMAW), and shielded metal arc welding (SMAW). However, it is important to use low heat input and slow cooling rates to avoid cracking and distortion. Preheating and post-weld heat treatment may also be necessary to achieve optimal results.


A 440c stainless steel bar is made by rolling an alloy of chromium, nickel, and molybdenum. These bars have a higher strength-to-weight ratio than other types of steel bars. 440c stainless steel round bar supplies are used in applications such as automotive, aerospace, and marine industries because they are corrosion resistant.

It helps make bearings, valves, cutting tools, and knives. Its hardness and wear resistance makes it suitable for high-temperature environments, where it can withstand abrasion and impact.

The 440C stainless steel bar also has good corrosion resistance, making it ideal for applications exposed to harsh environments or corrosive substances. Its excellent machinability and weldability make it a popular choice for manufacturing precision components and tools.

The 440c bar stock is a popular steel material for making bars. It manufactures many products, including car frames, railroad tracks, and aircraft parts.
