EXPERIMENTAL INVESTIGATION OF WELDING DISSIMILAR MATERIALS OF STAINLESS STEEL AND CORTEN STEEL

Weathering steel, often referred to by the exercised trademark corten steel and sometimes written without the hyphen as corten steel, is a group of steel alloys which were developed to eliminate the need for painting, and form stable rust like appearance after several years exposure to weather.

HSLA (High – Strength - Low – Alloy) steels mainly used for their higher strength and corrosion resistance. It has atmospheric corrosion resistance than Carbon steels. Stainless steel 316 and 316L are molybdenum – bearing austenitic stainless steel which are more resistance to general corrosion and pitting / crevice corrosion than the conventional chromium nickel austenitic stainless steel such as Type 304 . These alloys also offer higher creep , stress- to –rupture and tensile strength at elevated temperature. Type 316 and 316L generally contain 2 to 3%  molybdenum for improved corrosion resistance . Used for elevated temperature application and facades of buildings near the ocean.

Tests conducted:

• Hardness test
• Micro-structure
• Macro-structure

Cost of the Project: 20000 /-
