Most customers require specific metallurgical properties for their castings. Typically, one of the metallurgical properties specified is the chemical composition of the steel .Steels for forging quality are produced to a wide range of chemical compositions by basic oxygen process and electric arc furnace steel making processes. With each of the melting and rolling practices, a level of testing and evaluation quality is exercised. The details of testing and quality evaluation vary from producer to producer and should be a point of enquiry when the forging steels are ordered.
