At ABAC we use different materials to manufacture our fluid control accessories, the most common being stainless steel and carbon steel.
Each material has its particularities, linked to the application of the designed and manufactured products. Among them:
STAINLESS STEELS
They are alloyed steels such as chrome, nickel and other alloys. There are many variants depending on the chemical composition. The most used are:
• Martensitic: Type AISI 410, 420, 440.
– 13% Cr, without Ni.
– They are temperable
– They are magnetic
– Moderate corrosion resistance
• Austenitic: The most common are AISI 304 and 316.
– They have between 17% and 19% Cr, and 7% to 9% Ni (and Molybdenum).
– They are antimagnetic
– Cannot be quench hardened
– They have low mechanical resistance
– Resistance to most acids
• Duplex: They are steels from a combination of the two previous ones.
– They combine good corrosion resistance and high mechanical resistance.
– The best known is the SAF 2205 and the super duplex 2507.
• Precipitation Hardenable Martensitic: Combines corrosion resistance and high hardness after being heat treated.
– Excellent corrosion resistance, maintaining ease of machining.
– The most common is AISI630 17-4 PH.
CARBON STEELS
SAE 1012, SAE 1026, 1040/1045 steels, among others, are mainly used. And in forging, ASTM A105, equivalent to SAE 1026.
– Electroplating or zinc plating treatment is applied.
BRASS
It is a mixture of copper and nickel and other alloys.
PLASTIC MATERIALS
They are used for seals, packaging, seats, etc. The most common are PTFE, PEEK, PCTFE, Acetal, etc.
OTHER MATERIALS
In special applications, other materials may be required, such as:
• Monel-Hastelloy-Inconel: Non-ferrous, Nickel-based alloys with very high resistance to corrosion, especially at high temperatures.
– Widely used in environments with sulfur (“sour”).
