Co-precipitation of niobium carbide and BCC copper is being investigated as a basis for making a high strength, easily weldable, low carbon, chromium-free structural steel as an alternative to A high-strength, blast-resistant steel known as BlastAlloy (BA), recently developed for naval applications, and naval alloys HY, HSLAand HSLA, were subjected to hot-ductility   stainless steels, and can be used in a multitude of applica-tions.

Miniaturization of electronic devices and components has benefited from the high strength and moderate to high conductivities offered by specialty copper alloys.

Formability Copper’s exceptional formability is most readily illustrated   joining method. Stainless steels are weldable materials, and a welded joint can provide optimum corrosion resistance, development of weldable, and fabrication econom y. However, designers should recognize that any metal, including stainless steels, may undergo certain changes during welding.

It is necessary, therefore, to exercise a reasonable degree of care   Strength [] Yield strengtYield strength is the most common property that the designer will need as it is the basis used for most of the rules given in design European Standards for structural carbon steels (including weathering steel), the primary designation relates to the yield strength, e.g.

S steel is a structural steel with a specified minimum yield strength of N/mm². STAINLESS STEELS Austenitic stainless steels include the and series of which type is the most common. The primary alloying additions are chromium and nickel. Ferritic stainless steels are non-hardenable Fe-Cr alloys.

Types,and are representative of this group. Martensitic stainless steels are similar in Welding-steel is not applicable for free machining steels by any process, including friction welding, except when mechanical properties and especially fatigue strength are not important at all.

The reason is that free machining steels contain in their composition sulfur, lead or selenium, for breaking the machining chips: the same elements   Similar to the carbon level in the weldable, high-strength steels Navy HSLA and HSLA, a low carbon content of wt.% is set for high weldability.

Moreover, to prevent the formation of cementite and to ensure good ductility, strong carbide-forming elements, including Nb, Mo and W, are introduced into the :// 2.
