What is AISI 4140 Steel
AISI 4140 alloy steel round bar sheet plate belongs to medium hardenability steel.AISI 4140 steel has high fatigue strength and low notch sensitivity. Low-temperature impact toughness is also very high, no obvious temper brittleness. AISI 4140 steel round bar is mainly used after quenching and tempering state. it is used to manufacture high-strength parts under impact loads and the fittings with large cross-sections and other stressed members. Such as the horizontal eccentric shaft of the horizontal forging machine, the crankshaft of the forging press, and etc.
Its equivalent grade is JIS SCM440 and DIN 1.7225. The properties and composition of 4140 steel round bar sheet plate as below.

Stainless Steel Investment Casting
Stainless steel investment casting, also known as investment casting or lost wax casting, is a manufacturing process used to make complex metal parts of various shapes and sizes. The process involves pouring molten stainless steel into a ceramic shell or mold that is made by coating a wax mold with a ceramic material.
Concepts and Characteristics of Stainless Steel
Stainless steel is a chromium-containing iron alloy that provides a protective coating against fouling and corrosion. It performs well in liquid environments and is heat resistant at elevated temperatures. There are many different types of stainless steel, each containing a different chemical composition. The composition affects the mechanical properties and determines whether the material can be further strengthened by heat treatment.. They are widely used in aerospace, automotive manufacturing, chemical equipment, medical devices, and other fields.
