420 Modified Stainless Steel – Enhanced Strength and Machinability

Introduction to 420 Modified Stainless Steel

420 Modified Stainless Steel is a variation of standard 420 Stainless, offering improved strength, ductility, and machinability. While regular 420 Stainless Steel is primarily known for its hardness and corrosion resistance, 420 Modified is engineered to deliver superior mechanical properties, making it ideal for applications requiring higher strength and wear resistance. It is commonly used in industries such as medical, cutlery, and industrial tools where high durability is a must.

420F Stainless Steel – Free-Machining Grade for Precision Applications

Introduction to 420F Stainless Steel

420F Stainless Steel is a free-machining version of the 420 martensitic stainless steel. Known for its excellent machinability and ability to achieve high hardness through heat treatment, 420F is commonly used in applications that require precision machining without compromising on strength or corrosion resistance. It’s widely employed in industries such as medical devices, automotive, and industrial tools, where precise manufacturing is key.

Vincent Metals handles 430 in rod, sheet, strip, and foil.

430 is a ferritic stainless steel with corrosion, cracking, and oxidation resistance. 430 is formed with stretch forming, bending, and drawing operations. The high carbon of 430 stainless steel gives it poor weldability and it is non-hardenable due to its straight chromium content. 430 is heated and then quickly air-cooled, a process that prevents brittleness in the metal.

430 stainless steel is widely used in a variety of products:

• Dishwasher lining
• Automotive trim
• Chimney liners
• Machine parts
• Kitchen grade tables and utensils

Vincent Metals stocks and sells 430FR ASTM A-838 Alloy Type 2 Grade 1 in rod form.

430FR is ferritic stainless steel with an increased silicon content that allows it to possess increased magnetic characteristics and higher electrical resistivity. It is ideal for parts that require corrosion resistance, such as:

• Solenoid valves
• Injectors

430 FR maintains its corrosion resistivity in fresh water, moderately acidic, and low chlorine environments. 430FR’s increased hardness and magnetic characteristics make it a good choice for several industries:

• Aerospace
• Automotive
• Industrials

We stock and sell Biodur 108 in rod form.

BioDur 108 is a tough, non-magnetic material frequently used for medical purposes. BioDur 108 is hardened through cold working, a process in which metal is shaped while at its ambient temperature. This metal is nearly nickel free, cobalt free, and FDA approved for implantable medical devices. BioDur 108’s non-magnetic composition makes it MRI friendly, and its low nickel status makes it safer for metal sensitive individuals than other stainless steels. A few of BioDur 108’s medical uses include:

• Bone plates
• Bone screws
• Hip and knee parts
• Orthodontic appliances
• High strength surgical instruments

BioDur 108’s high nitrogen and low nickel content gives it improved fatigue strength in comparison to nickel-containing alloys. It is a metal great for metal sensitive individuals and large-scale production alike.
