Surface treatment of stainless steel Stainless steel is used in fact due to its specific corrosion resistant features. This corrosion resistance is the result of its natural capacity to form a protective oxide film. This oxide film is however extremely thin and therefore very vulnerable. Many of the treatments that the stainless steel undergoes in […]
This is the 1936 Ford Tudor Sedan built for and owned by Allegheny Ludlum Steel. This is 1 of only 4 in existence and is the only one currently in running and; in road worthy condition. The car is in exceptional condition, with the interior and even the frame looking great. All 4 car each had over 200,000 miles on them before they removed them from service.
These cars were built for Allegheny as promotional and marketing projects. The top salesmen each year were given the honor of being able to drive them for one year. The v-8 engine (max 85 hp) ran like a sewing machine and was surprisingly smooth and quiet. The car was insured (we were told) for the trip to Louisville via covered trailer for 1.5 million dollars.
We were also told that the dies were ruined by stamping the stainless car parts, making these the last of these cars ever produced.
Stainless steel has a high thermal expansion, but a low thermal conductivity so the heat localizes and the expansion/contraction is magnified.
- Perfect joint fit-up.
- Tiny tacks every 1/2?
From rockwelder.com a fine selection of handrail pictures. Excellent design fabrication and welding.
A Thermic Lance is a steel pipe packed with mixed metal wires. Pure oxygen gas is passed through the pipe from an oxygen cylinder and regulator. The end of the pipe is lit with a high temperature source, e.g. an oxy-acetylene torch. The iron in the steel burns in the oxygen coming down the pipe to produce enormous heat. Read More

7018 welding rods allow very little hydrogen into the weld pool unless they have moisture in them from not being stored correctly. Moisture allows hydrogen into the flux, which is then introduced into the weld pool adversely. What happens is the moisture is superheated and then bubbles up to the surface leaving an open pocket […]
The LN-25 semiautomatic wire feeder is ideal for field or construction use. Since it is powered across the arc, no control cables are needed! Simply connect the weld cable, attach the welding clip, and you
