Lastifil 8003

Welding of dissimilar metals

High alloyed stainless steel welding wire for joining dissimilar metals.

Recommended for joining martensitic and ferritic steels if preheated up to 200 – 300 °C (390-570 °F).

Suitable for working temperatures up to 300 °C (570 °F) (“black-and-white” assemblies).

Oxidation resistant up to 1.000 °C (1.830 °F).

Specifications & Usage

Application

Joining austenitic and ferritic stainless steel to low- and unalloyed steel (17Mn4, StE355, ...).

Tough, crack-resistant underlayers for hardfacings.

Stainless surface coatings on unalloyed steel (rustproof from the first layer).

Refacings with a low frictioncoefficient.

Instructions

Clean the weld area thoroughly and eliminate all traces of oil and grease.
