UGIMA® 4511 Annealed
UGIMA® 4511 Annealed introduction
UGIMA® 4511 is an improved machinability niobium-stabilised ferritic stainless steel containing between 16 and 17% chromium.
Apart from good corrosion resistance, this grade is characterised by its high suitability for different methods of working such as machining, cold heading and welding:
This UGIMA® version of 4511 enables bar turning productivity significantly greater than that obtained with a standard 4511 to be achieved, as well as good chip breakability.
Stabilisation with niobium eliminates the risk of sensitisation during welding.
It has excellent cold-heading properties.
For certain applications, it is an economical replacement for 1.4307.
Its ferritic structure ensures excellent ferromagnetic properties, good oxidation resistance (in particular to thermal cycles) and an expansion coefficient similar to that of carbon steel.
The structure of UGIMA® 4511 is entirely ferritic in the as-delivered condition. The main precipitates are Nb-carbonitrides and Mn-sulphides.
Ugima® 4511 is a soft ferromagnetic material (it is attracted to a magnet). Magnetic annealing is used to optimise its magnetic properties and therefore achieve high relative permeability and low coercive fields. This treatment can be carried out either on bars produced by Ugitech or on machined parts.
Equivalent material: DIN 1.4511, EN 1.4511, AISI 430, AFNOR X3CrNb17
