AISI 8630, AISI 4340, AISI 4130, AISI 6150

November 1, 2011

AISI 4130, a chromium-molybdenum alloy used widely as an aircraft steel, combines weldability, ease of fabrication and mild hardenability. Best used for welded tube fuselages. It can also be used to make car connecting rods, engi... Read More...

High Strength Low Alloy Steels HSLA

July 5, 2011

High strength low alloy (HSLA) steels are a group of low carbon steels that utilise small amounts of alloying elements to attain yield strengths in excess of 550 MPa in the as-rolled or normalised conditions. These steels have ... Read More...

Notes on alloying elements

July 5, 2011

Aluminium Range 0-2%..This increases resistance to oxidation and scaling, aids nitriding and restricts grain growth. Chromium Range 0,3% to 4% ..Improves wear, oxidation and scaling resistance and hardenability but increase... Read More...

Relative effect alloying elements

July 5, 2011

The combined effect of alloying elements results from many complex interactions resulting from the processing history, the number and quantities of constituents, the heat treament, the section shape etc etc..  Some basic rule... Read More...

Carbon Alloy Steel

July 5, 2011

Carbon steels usually contain less than 1,2% carbon and small quantities of manganese, copper, silicon, sulfur, and phosphorus    Alloy steels are carbon steel with other metals added specifically to improve the properties o... Read More...
