Description

AQUAMET 19 is currently in wide use in pleasure boats, workboats, crew boats, fishing trawlers, pilot and patrol boats.
Grade Aquamet 19 is usually taken a special steelmaking technique by BEF & AOD followed by electroslag remelting (ESR) / VAR if necessary for special purpose.
Bars and, where applicable, forgings are subjected to ultrasonic examination based on the different levels according to the buyers' requirements.

Heat Treatment Practice
Heat treatment is only suitable for specific grades of 
stainless steel. When heat treating a stainless the hardening temperatures, including rate of heating, cooling and soaking times will vary due to several factors such as the shape and size of each component. Other considerations during the heat treatment process include the type of furnace, quenching medium and work piece transfer facilities. Please consult with the heat treatment provider for whole guidance on heat treatment of stainless steel grades. We are delighted to help to work with you the special heat treatment based on your special requirements.
