BÖHLER A903 (UNS S32205) is the most common stainless ferritic-austenitic Cr-Ni-Mo steel with nitrogen addition. In addition to good strength properties, this steel offers high corrosion resistance, especially against stress corrosion cracking in chloride-containing solutions, and is resistant to intergranular corrosion up to 300°C. The alloy should not be used at temperatures above 300°C due to embrittlement. Heat treatment after welding is not necessary. Required surface finish: pickled, scale-free heat treated or machined. Commonly used in the oil and gas industry, hydroelectric power, pressure vessels, pulp and paper industry, components and chemical tanks, such as parts for separators and heat exchangers and parts in the paper industry, oil and gas extraction , compressors, seawater desalination.

BÖHLER A911SA is a ferritic-austenitic stainless steel of Type 25%Cr with PREN of min. 40. It offers excellent corrosion resistance against general corrosion, stress corrosion cracking, corrosion fatigue, pitting, crevice and erosion corrosion and possessing very high mechanical strength properties. However, it contains less copper compared to other super Duplex SS but a deliberate addition of tungsten instead, claimed to selectively improve corrosion resistance. Good weldability, post weld heat treatment not necessary. Max. temperature for long periods of service: 280°C (535°F ) / (300°C/570°F possible for short periods). Surface condition for optimum corrosion resistance: pickled or machined. Components in offshore, waste water, sea water desalination and chemical plants with aggressive chloride-containing media e.g. heat exchangers, separator parts, compressor and pump components, turbine blades.

BÖHLER M303 is a corrosion-resistant, martensitic chromium steel with very good toughness, corrosion resistance, good wear resistance and improved machinability and polishability. Compared to 1.2316, BÖHLER M303 has better homogeneity and is approved for food and beverage contact.

BÖHLER M333 ISOPLAST is a corrosion-resistant, martensitic plastic mold steel with excellent polishability and toughness for products with highest surface requirements. BÖHLER M333 ISOPLAST is also approved for food and beverage contact.

BÖHLER N700 is a high-quality corrosion-resistant steel in aerospace quality, in the form of bars, wire and forgings with a diameter/thickness of up to 203 mm in the solution-annealed condition, as well as starting material of any size for forging purposes. It is a martensitic, precipitation-hardenable chromium-nickel-copper steel with high strength and toughness. Further increases in strength can be achieved by cold forming and subsequent precipitation hardening. These products are typically used for parts requiring corrosion resistance and high strength up to 316°C. However, their use is not limited to such applications. However, use is not limited to such applications. Certain processing methods and operating conditions can cause these products to become susceptible to stress corrosion cracking. For applications such as bolting where stress corrosion cracking is possible, the product should be aged for a minimum of 4 hours at the highest temperature compatible with the strength requirements, but in no case lower than 552°C.

BÖHLER N700 AMPO (17-4 PH) is a precipitation hardening nickel martensitic steel. Thanks to its alloying system, this material has excellent corrosion resistance. Can be printed very easily without additional heating of the platform or chamber and, after solution annealing and aging, hardens up to approx. 40 HRC.

BÖHLER N700 SA is a premium aerospace-quality corrosion-resistant steel available in bars, wire, and forgings with diameters/thicknesses up to 203 mm in the solution-annealed condition, as well as starting material of any size for forging purposes. It is a martensitic, precipitation-hardenable chromium-nickel-copper steel with high strength and toughness. Further strength increases can be achieved through cold working and subsequent precipitation hardening. These products are typically used for parts requiring corrosion resistance and high strength up to 316 °C, but their use is not limited to such applications. Certain processing methods and operating conditions can make these products susceptible to stress corrosion cracking. For applications such as bolted joints where stress corrosion is possible, the product should be aged for at least 4 hours at the highest temperature compatible with the strength requirements, but in no case lower than 552 °C.
