400-Series Stainless Steels Overview

The 400 series stainless steel is a high-strength, cost-effective alloy with higher carbon and chromium but no nickel. It offers greater hardness and strength than the 300 series, making it ideal for exhaust systems, agricultural parts, and surgical tools. BESSER delivers precise 400 series castings for applications demanding strength, wear resistance, and magnetic properties.

Advantages of 400-Series Stainless Steels

FAQs About 400-Series Stainless Steel Casting

Get the answers you need about 400-series stainless steel casting here.
What is the main difference between 400-series and 300-series stainless steel castings?
400-series stainless steels are primarily martensitic and ferritic, offering higher strength and wear resistance but lower corrosion resistance than the austenitic 300-series.
What are the corrosion resistance properties of 400-series stainless steels?
Generally, 400-series stainless steels have moderate to low corrosion resistance. Ferritic grades like 430 and 446 offer better corrosion resistance than martensitic grades due to higher chromium content.
Can BESSER provide customized stainless steel castings?
Yes, we specialize in providing custom stainless steel castings, tailored to meet your specific design and material requirements.
Can you produce small batch orders?
Yes, we can handle both large-scale and small-batch production, ensuring flexibility in meeting the needs of different clients. We specialize in producing high-quality custom parts, whether in small quantities or for large-volume orders.
Do you offer post-casting services?
Yes, BESSER provides additional post-casting services, including CNC machining, surface treatments (like polishing, electroplating, and coating), and heat treatment, to meet specific client requirements.
