Compare ASTM A193 Grade B8 Bolts price with ASTM A193 Grade B6 Bolts price list
Ordinarily, stainless steel alloy 304 does not contain molybdenum and copper in its alloy. However, Grade B8MLCuN includes a significant content of molybdenum with copper. Furthermore, the content of nitrogen is permitted to have a higher range in Grade B8MLCuN as compared to the conventional A198 Gr. B8 Socket Head Cap Screws. Another point of distinction is the content of carbon in both alloys, while grade ASME SA193 Grade B8 Hex Bolts may contain 0.08% carbon, the alloy for Grade B8MLCuN would contain a max carbon content of 0.02%. Grade B8 bolts are available in the market in two classes. Both classes are treated to a solution annealing process.
Class 2 is generally treated to a Strain hardening process where the astm a193 b8 threaded rod is hardened by plastic deformation of alloy 304. During plastic deformation of the material for astm a193 grade b8 bolts, the crystalline structure of the alloy tends to get dislocated internally. On the other hand, the carbide solution treatment or solution annealing treatment given to ASTM A193 B8 Class 1 Bolts improve their mechanical properties. The usefulness of solution annealing the SA193 B8 Threaded Rod is seen in instances where the materials may be exposed to elevated temperatures. Elevated temperatures often cause intergranular corrosion in stainless steel alloys. By using a solution annealing treatment, it is possible to eliminate unwanted phases/carbides in the ASTM A193 B8 Heavy Hex Bolts alloy. Furthermore, if the SA 193 Gr B8T Material is to be welded, the rate of corrosion is delayed due to solution annealing.

Grade 304 is one of the most highly sought after materials for the production of several components including bolts. B8 bolts in astm a193 b8 stud bolts are known to be synonymous with stainless steel 304. Ordinarily, the alloy for 304 has a sa 193 gr b8 chemical composition of chromium and nickel in the ratio 18/8. Therefore in several industries, many manufacturers may also refer to the ASTM A193 B8 Class 2 Material in terms of its chemical composition. Since austenitic stainless steels, in particular, those belonging to the 300 series could have their chemistry altered, it is possible to produce a fastener such as ASTM A193 B8MLCuN Stainless Steel Bolts Specification.
