Studbolts

Highly creep and corrosion resistant, precipitation hardening austenitic steel. Scaling resistance in air up to appr. 800°C.

Ferritic-austenitic stainless steel. Excellent corrosion resistance against general corrosion, stress corrosion cracking, corrosion fatigue, pitting, crevice and erosion corrosion and possessing very high mechanical strength properties.

High temperature, precipitation hardening, nickel-base alloy with particularly high hot strength and yield strength up to 750°C, and excellent creep behaviour up to 700°C. The markedly higher hot strength compare with normal hot work steels in particularly noticeable when used for hot work tools with high mechanical and thermal stresses.

Is a non-magnetic, corrosion and oxidation – resistance, nickel based alloy. High toughness and strength in the temperature range cryogenic to 1000°C. The alloy as excellent fatigue strength and stress corrosion cracking resistance to chloride ions.

Is as age-hardenable nickel-iron-chromium alloy. Is used in various applications requiring a combination of high strength and corrosion resistance.

Is a solid-solution alloy that can be hardened only by cold working. It has high strength and toughness over a wide temperature range and excellent resistance to many corrosive environments. It is widely used in many fields, especially marine and chemical processing.

Is a nickel-copper alloy with combines the excellent corrosion resistance of Monel 400 with the added advantages of greater strength and hardness. The increased properties are obtained by adding aluminium and titanium to the nickel-copper base by heating.

Ferritic-austenitic stainless steel also referred to as DUPLEX STAINLESS STEELS, combine many of beneficial properties of ferritic and austenitic steels. Due to the high content of chromium and nitrogen, and often also molybdenum, these steels offer good resistance to localised and uniform corrosion. The duplex microstructure contributes to the high strength and high resistance to stress corrosion cracking.

A Super Duplex stainless steel is a type of Duplex stainless steel with enhanced corrosion resistance which is categorised by its PREN being greater than 40. The Pitting Resistance Equivalent Number (PREN) is widely used as a means of comparing the relative corrosion resistance of different steel grades.
