Did you know that tubes and fittings material account for as much as 90% of the fluid's surface contact throughout the entire process flow?

It is therefore important to choose the right material for your application. Below you can read about the different types of material you can choose within our fitting’s portfolio.  

What are the types of stainless-steel material available for fittings?

What is 1.4301 (304)?

EN 1.4301, also known as AISI 304. The most widely used stainless steel grade in the world. This grade is used at least one third of all stainless-steel products. This grade can be also shown as 18-8 or 18-10 and these numbers indicate the chromium and nickel percentages of the material. 

304 grade stainless steel has a really good price/performance and because of its good price/performance, 304 grade used very widely in many different applications. 

What is 1.4307 (304L)?

EN 1.4307, also known as AISI 304L, is a type of stainless steel that is versatile and durable. It is a low carbon version of AISI 304 with a high percentage of chromium, which provides superior corrosion resistance. 

It also contains small amounts of carbon and manganese, which improve resistance to oxidation. EN 1.4307 / AISI 304L is known for its excellent weldability and corrosion resistance and is suitable for use in both hot and cold working environments. It is widely used in the food industry and is a cost-effective alternative to AISI 316L

What is 1.4401 (316)? 

EN 1.4401, also known as AISI 316. 316 stainless steel contains an addition of molybdenum that gives it improved corrosion resistance. This is particularly apparent for pitting and crevice corrosion in chloride environments.

What is 1.4404 (316L)?

EN 1.4404, also known as AISI 316L, is an austenitic stainless-steel type with superior corrosion-resistant properties and is a low carbon alternative to AISI 316. AISI 316L is softer, more flexible, and offers higher levels of corrosion resistance than AISI 316. 

The difference in carbon content between AISI 316 and 316L results in different strengths and uses, with AISI 316L being widely used in the pharmaceutical industry due to its superior durability when welded and high resistance to corrosive chemicals
