Core 305/4303 is a high-nickel alternative to Core 304/4301 with reduced strain hardening and excellent cold forming properties. Ideal for parts that require high deformation degrees.

Core 305/4303 is an austenitic stainless steel that belongs to the standard CrNi stainless steel family. It has 12.5 wt.-% nickel for improved formability.

The austenitic CrNi standard grades are the most widely used group of stainless steels. Their well-balanced material properties make them suitable for the fabrication of many products. Core 305/4303 is available in many product forms and dimensions. It can be supplied with a wide range of functional and aesthetic surface finishes.

Core 321/4541 is a titanium-stabilized austenitic stainless steel with improved intergranular corrosion resistance for an extended temperature range. Core 321/4541 is an austenitic stainless steel that belongs to the standard CrNi stainless steel family. Core 321/4541 can be welded in all dimensions without becoming susceptible to intergranular corrosion.

The austenitic CrNi standard grades are the most widely used group of stainless steels. Their well-balanced material properties make them suitable for the fabrication of many products. Due to its titanium content, Core 321/4541 can be used at elevated temperatures. For high-temperature applications, the use of the optimized high-temperature Therma 321H/4878 is recommended.

Core 321/4541 is available in many product forms and dimensions, often also from many stainless steel stockholders. Polishing of Core 321/4541 is limited due to its titanium alloying.

Core 347/4550 is a niobium stabilized alternative Core 321/4541 with improved intergranular corrosion resistance and good mechanical properties at high temperatures. Core 347/4550 is particularly useful in applications with intermittent heating in the range 400–900 °C/750–1650 °F. Core 347/4550 is an austenitic stainless steel that belongs to the standard CrNi stainless steels. Core 347/4550 can be welded in all dimensions without becoming susceptible to intergranular corrosion.

The austenitic CrNi standard grades are the most widely used group of stainless steels. Their well-balanced material properties make them suitable for the fabrication of many products.

Core 441/4509 is a nickel-free 17% chromium ferritic stainless steel originally designed for exhaust systems, with good corrosion resistance and high-temperature strength. Core 441/4509 is available with a single (niobium) or dual (niobium and titanium) stabilizer. Due to good formability and weldability, it is often a suitable replacement for Core 301/4310.

Core 441/4509 can be supplied with a wide range of functional and aesthetic surface finishes.

Core 4622 is a nickel-free, high-chromium (21Cr) ferritic stainless steel with equal corrosion resistance to Core 304/4301. Core 4622 has excellent deep drawability and is almost ridging free, meaning it is easier to polish and has a lower overall production cost.

Core 4622 is a 21% chromium ferritic stainless steel, which can be used in many corrosive environments. Because of its titanium and niobium alloying, Core 4622 can be welded in all dimensions without becoming susceptible to intergranular corrosion. It is possible to use Core 4622 at elevated temperatures, like for instance in automotive exhaust systems. Core 4622 can be supplied with a wide range of functional and aesthetic surface finishes.

Outokumpu Therma 4622Nb™ (EN 1.4622) dual stabilized ferritic stainless steel has enhanced high temperature creep resistance above 1000°C due to alloying of niobium and silicon. Thanks to its high chromium content improved corrosion resistance is achieved. That makes it ideal for a wide range of applications such as automotive exhaust systems, furnace equipment, annealing boxes, air heaters and burner nozzles. Therma 4622Nb™ fulfils ASTM UNS S44330.

Therma 4622Nb™ has:

• Good corrosion resistance Comparable to common austenitic grades, such as 304L (EN 1.4307).
• Competitive and stable price 
• Excellent cost stability compared to Ni-alloyed austenitic grades and Mo-alloyed acid proof grades.
• Deep drawable Ideal for deep drawing applications with high R-value and limiting drawing ratio (LDR).
• Good weldability
• Low risk of sensitization due to stabilization. Less distortion than in austenitic grades due to higher heat transfer. 
• Good machinability
• Lower work hardening versus austenitic grades.
