Steel grades of 18CrNiMo7-6

18CrNiMo7-6 is a case-hardening steel known for its exceptional toughness. There are several variants of this steel that have stringent cleanliness requirements and possess narrower composition ranges compared to the standard version. One specific variant, designated as IQ (isotropic quality), is produced to have an extremely low number of elongated sulfide inclusions, resulting in more isotropic properties. The high level of oxidic cleanliness in this variant allows it to meet the same demanding cleanliness standards as re-melted qualities.Grade 159A: This variant has a low sulfur content and is designed to meet high cleanliness requirements.Grade...

ASTM A278 class 35C Properties and Aplications

ASTM A278 class 35C is a grade of carbon steel and low alloy steel castings that has a minimum tensile strength of 35,000 psi (240 MPa), a minimum yield strength of 22,000 psi (150 MPa), and a minimum elongation of 22%. This grade of cast steel is commonly used in general-purpose applications that require good strength and toughness, as well as resistance to wear and corrosion. In ASTM A278, the letter "C" following the numerical value, such as "35C", indicates that the material is a carbon steel casting. The "C" designation is used to distinguish carbon steel castings from other types of castings, such as alloy steel or stainless-steel castings,...
