Mahendra Metals & Tubes Company is one of the renowned exporter and trader of manufacturer of XM-19 Round Bars , which has outstanding resistance to hydrochloric acid at all concentrations and temperatures. Phosphorus has a strongly embrittling effect in these alloys and decreases weldability (hot shortness and crack formation). Therefore phosphorus content is kept as low as possible.
These additions make XM-19 Flat Bars age-hardenable. Chromium increases strength and has a surprisingly favourable effect on resistance to erosion corrosion in fast-flowing seawater and to erosion by solids. Aluminium increases strength, seawater and scaling resistance. Beryllium has the strongest effect on mechanical properties after age-hardening.
The solubility of carbon in nickel is severely reduced as copper content increases – it is about 0.01 % with a copper content of 90 %. Carbon is not detrimental in these alloys. Cobalt can often occur as an uncontrolled constituent in these XM-19 Hex Bars offered by Mahendra Metals & Tubes Company depending on the cobalt content of the nickel used.
Antimony, arsenic, sulphur, tellurium and bismuth are embrittling in small quantities, alone or in combinations, and should not be present in practice in these alloys. Further addition elements in XM-19 Sheets of Mahendra Metals & Tubes Company are indicated in the identification symbol by attaching the chemical symbol and very often by stating the mean contents. XM-19 Plates offered by Mahendra Metals & Tubes Company can be most effective under high temperatures and corrosive environments, with high stress resistance.
