Nearly all of the vessels are ASME Code vessels made using one of the carbon steel grades with typical design conditions of 175E to 180EC (350E to 360EF) and 150 psig. These vessels had a very good service record with only isolated reports of cracking problems until the occurrence of a sudden rupture failure in 1980.

Martensite gives steel great hardness, but it also reduces its toughness and makes it brittle, so few steels are fully hardened. There are also other grades of stainless steels, such as precipitation-hardened, duplex, and cast stainless steels. Stainless steel can be produced in a variety of finishes and textures and can be tinted over a broad ...

Final hardness is at the die caster’s discretion and should be selected based upon steel grade, size, and die design. Do not temper below 1000° F (540° C). Lower hardness is specified for larger tools to give better toughness. High hardness (up to 52 HRC): Increased wear resistance and better resistance to heat checking.

In addition to the the indicated grade marking, all grades included in this table must be marked for manufacturer identification. While hex heads are shown, grade markings apply equally to products with other head configurations. Brinell hardness numbers are shown for A490 Type 1 bolts over 1-1/2 inch thru 3 inch.

Hardness is generally measured by relating the depth of penetration of a standard penetrator, eg a steel ball or a pyramid-shaped diamond tip, pressed against the surface of the material being tested with a known force. Various hardness testing systems are available, those in common use being. the . Brinell Hardness. and . Rockwell Hardness ...
