Nickel-molybdenum alloy B-2 has extremely low carbon and silicon content, which reduces the precipitation of carbon and other impurity phases in the welding heat-affected zone, so its welds also have sufficient corrosion resistance.
Alloy B-2 has good corrosion resistance in reducing media, such as hydrochloric acid solutions of various temperatures and concentrations. It also has good corrosion resistance in moderately concentrated sulfuric acid solutions (or containing a certain amount of chloride ions). It can also be used in acetic acid and phosphoric acid environments.

Hastelloy B-2 platesare widely used in the chemical, petrochemical, energy manufacturing and pollution control fields, especially in the sulfuric acid, hydrochloric acid, phosphoric acid, acetic acid and other industries. If used in special fields, please consult material supplier Wuxi Walmay Metal Co, Ltd.
The welding performance ofB-2plateis similar to that of ordinary austenitic stainless steel. Before using a welding method to weldB-2, measures must be taken to minimize the decrease in corrosion resistance of the weld and heat-affected zone, such as Gas tungsten arc welding (GTAW), gas metal arc welding (GMAW), submerged arc welding or other welding methods that can minimize the corrosion resistance of the weld and heat-affected zone.
The manufacturing process of stainless steel and alloys involves multiple steps to transform raw materials into flat,rectangular sheets or plates made of stainless steel and alloys. Here are a few key steps for stainless steel and alloys:
Molten stainless steel and alloys are cast into large ingots or billets through a casting process.
During the hot rolling process,the thickness of the steel ingot is gradually reduced and elongated to form long strips or coils.
Annealing involves heating stainless steel and alloys to a specific temperature and then slowly cooling it.
Cold rolling is carried out through rolling mills to reduce thickness to meet customer specifications.
