The present invention provides a method for heat-treating seam-welded constructions of hardenable steel and ferrous alloys with reduced weld-zone hardness and improved weld-zone ductility and toughness This method consists of heating the seam weld rapidly with a secondary heat source to a temperature greater than the martensitic start temperature but not greater than the lower critical temperature, followed by immediately allowing the seam weld to air-cool The rapid tempering of this invention is particularly suited to the production of high strength hardenable alloy seam-welded pipe and tubing and other structures

Method for improving the performance of seam-welded joints using post-weld heat treatment

A method for making structural automotive components and the like includes providing a blank of air hardenable martensitic stainless steel in the annealed condition. The steel blank has a thickness in the range of 0.5-5.0 mm., and is formed utilizing stamping, forging, pressing, or roller forming techniques or the like into the form of an automotive structural member. The automotive structural member is then hardened by application of heat, preferably to between 950° C. and 1100° C. for standard martensitic stainless steels. Thereafter, the automotive structural member is preferably cooled at a rate greater than 25° C. per minute to achieve a Rockwell C hardness of at least 39. The automotive structural member may undergo additional heat treating processes including high temperature or low temperature tempering processes which may incorporate electro-coating.

An improved method of depositing nickel on a clean refractory metal surface to form a multilayer article is disclosed, wherein the full thickness of nickel can be plated prior to the intermetallic bonding of the metals The metal surface is cleaned and etched prior to the application of a first layer of nickel on the surface by electroplating means After the article is rinsed, a second layer of nickel is applied to the first layer of nickel by electroplating means The article is then heated in the absence of air to cause intermetallic bonding between nickel and the refractory metal substrate

Nickel plating of refractory metals

A steel sheet plated with Pb-Sn alloy, suitable for use as the material of automobile fuel tanks for containing fuel having alcoholic content. The steel sheet has an NiSn alloy layer or a composite layer including a backing Ni layer and the NiSn alloy layer; the NiSn alloy layer or the composite layer being formed on the steel surface to have a thickness of 0.035 to 1μ; and a plating layer of Pb-Sn system alloy formed on the sole NiSn layer on the NiSn layer of the composite layer. The steel sheet plated with Pb-Sn alloy can be produced by plating the steel sheet with Ni backing, forming a Pb-Sn system alloy layer by a hot dip plating, and rapidly cooling the steel sheet. Alternatively, the steel sheet plated with Ni is subjected to successive electroplating with Sn and then with Pb, and is then treated at a specific temperature for melting and diffusing Sn into Ni to form the NiSn layer.

Method of plating ironnsteel material with molten leaddtin alloy

A steel member for example a steel sheet coated with Pb-Sn alloy, suitable for use as the material of automobile fuel thanks for containing fuel having an alcohol content. The steel member or sheet has an NiSn alloy layer or a composite layer including a backing Ni layer and the NiSn alloy layer; the NiSn alloy layer or the composite layer being formed on the steel surface to have a thickness of 0.035 to 1 p; and a coating layer of Pb-Sn system alloy formed on the sole NiSn layer or the NiSn layer of the composite layer. The steel member or sheet coated with Pb-Sn alloy can be produced by coating it with Ni backing, forming a Pb-Sn system alloy layer by a hot dip coating, and rapidly cooling the stell sheet. Alternatively, the steel member or sheet coated with Ni is subjected to successive electroplating with Sn and then with Pb, and is then treated at a specific temperature for melting and diffusing Sn into Ni to form a NiSn layer.
