Product Description

Materials -Bolts in ASTM A193 and Nuts in ASTM A194 (All Grades)

Scope

ASTM A193 is the standard specification for alloy-steel and stainless steel bolts used in high-temperature or high-pressure environments or other special-purpose applications. ASTM A194 is the standard specification for carbon and alloy steel nuts for bolts used in equivalent high-pressure or high-temperature environments. ASTM A193 and A194 bolts and nuts from Glaser and Associates are available in a range of grades, including B7, B16 B8 and B8M to meet different design, service conditions, mechanical properties, and high temperature requirements. ASTM A194 also covers the American Association State Highway and Transportation Officials Standard AASHTO M-292.

These bolts and nuts are designed, manufactured and tested to comply with the standards set by ASTM A193 and A194 for chemical composition, tensile and hardness properties and high temperature characteristics.

Grades

Material

B7

Alloy steel, AISI 4140/4142 quenched and tempered

B16

Alloy steel, Chromium-molybdenum-vanadium heat treated

B8

Class 1 Stainless steel, AISI 304, carbide solution treated

B8M
