Like the rest of the automotive industry, bus manufacturing is going through changes and experimenting with new materials. What kind of benefits can stainless steel bring to modern bus designs? Our Lead Technical Manager Barbara Mundt presents some examples.

Dura 4024 is a martensitic grade with slightly increased hardenability compared to 1.4006. Corrosion resistant in water and steam. For mechanical engineering applications and surgical instruments.

Dura 4110 is a high hardness martensitic stainless steel (compared to 1.4034), but with improved corrosion and wear resistance. It is applied for, e.g., knife blades, scissors, surgical cutting tools, measuring tools, pump construction, valves.

Dura 420/4021 is a very popular martensitic grade. It is corrosion resistant in water and steam. It is used in low-medium hardness for applications such as cutting utensils, surgical instruments, press plates, brake discs and mechanical parts.

Medium-hardness martensitic grade. Corrosion resistant in water and steam. Applied for cutting utensils, surgical instruments, measuring tools, mechanical parts esp. subject to wear.

Martensitic grade with medium-high hardness . Corrosion resistant in water and steam. Applied for cutting utensils, surgical instruments, measuring tools, mechanical parts subject to wear.

Circle Green® is the world’s first towards zero carbon stainless steel. It has the lowest carbon footprint in the industry.

Similar to 1.4110, but with elevated wear resistance. Applied especially for cutting instruments which undergo partial hardening for excellent wear resistance of functional surfaces.

High-hardness martensitic grade. Corrosion resistant in water and steam. For e.g. professional kitchen knives, top-quality knives, surgical instruments, press plates, brake disks.
