Boiler & Pressure Vessel Steel to ASTM / ASME Standard

ASTM/ ASME are the standards more widely used in South America. PHIONE Limited is the leading supplier of carbon and low alloy steel plate for pressure vessels and boilers in South America and Spain. 

Our main grades are:


Carbon Steel for Low and Intermediate Tensile Strength


Alloy Steel (Chromium-Molybdenum)


Carbon Steel for Intermediate and Higher Temperature Service


Carbon Steel for Moderate- and Lower-Temperature Service

However, carbon and low alloy steels may be susceptible to cracking when exposed to corrosive H2S containing environments, usually referred to as 'sour service'. If you require more resistant steels we can supply plates with resistance to HIC (Hydrogen Induced Cracking), meeting the requirements of NACE MR 0175 for HIC resistance. Please contact us to discuss these requirements.
