Valčekové ložiská odolné voči korózii, závitovkové prevodovky i konštrukčné diely odolné voči korózii, napr. pre letecký priemysel, zdravotnícku techniku, farmaceutický, potravinársky priemysel a priemysel syntetických materiálov.

Všetky druhy strihacích a rezných nástrojov, ktoré vyžadujú vynikajúcu odolnosť proti korózii, ako sú chirurgické rezacie nástroje, príbory, čepele rôznych tvarov s vysokou tvrdosťou a húževnatosťou, taktiež pre komponenty vyžadujúce odolnosť proti opotrebeniu.

Kalené nástroje s vysokou trvanlivosťou ostria, napr. čepele nožov, rezacie chirurgické nástroje, tanierové nože pre mäsopriemysel, nože a misky váh, valčekové ložiská odolné voči korózii, ihly ventilov a piesty chladiarenských strojov.

BÖHLER N695 is a corrosion-resistant, martensitic chromium steel with a high carbon content and added molybdenum.

BÖHLER N700 is a martensitic, corrosion-resistant, 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 that require higher corrosion resistance than the usual 13% or 17% chromium steels and high strength. Various remelting processes are used to improve steel purity and homogeneity. (ESR, PESR, VAR). Certain processing methods and operating conditions can make these products susceptible to stress corrosion cracking. For applications such as bolting where stress corrosion cracking 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. Typical engineering applications include surgical and dental instruments as well as aerospace components, reactor construction, highly stressed pump parts, springs and ship shafts.

P511 – Nenamagnetizovateľná oceľ

BÖHLER P513 is a weldable, non-magnetic, austenitic stainless steel with resistance to seawater and intercrystalline corrosion. It offers the best abrasion resistance of all stainless steels. The corrosion resistance of BÖHLER P513 is better than that of conventional austenitic Cr-Ni steels (type 304), and even better than Cr-Ni-Mo steel (type 316) under standard test conditions against chloride pitting, stress corrosion cracking and crevice corrosion. BÖHLER P513 is an alloy with a high silicon and manganese content and added nitrogen, which also works well at high temperatures around 1800 ºF. Silicon and manganese prevent wear and scuffing even in the annealed condition. Higher strengths can be achieved by cold forming, but this does not significantly improve abrasion resistance. BÖHLER P513 is used in the aerospace, food and pharmaceutical, oilfield, petrochemical, surgical and chemical industries, e.g. for valve stems and valve seats, fastening systems, shielding, chain drive systems, pins, bushings and roller bearings, wear rings and pistons in pumps.
