Sandvik Materials Technology has announced the addition of three new grades to its range of stainless steel tube and pipe for high temperature applications.

The new grades, designated 1C 256 (W.Nr 1.4724), 1C 356 (W.Nr 1.4742) and 2C48 (ASTM TP 446.2), are ferritic stainless steels with high chromium content. Added to Sandvik's existing range of austenitic stainless steel grades, they provide end-users and equipment suppliers in the steelmaking, petrochemical, furnace and power industries with an expanded range of selection options for high temperature materials depending on service conditions, service life, maintenance and cost requirements.

Typical applications for the new grades are recuperators and air heaters for the glass, carbon black, steel and waste incineration industries, muffle tubes for wire drawing and pyrometer tubes for the furnace industry.

The new ferritic grades 1C256 and 1C356 are particularly well suited to use as recuperator tubing in flue gases containing a certain level of sulphur at operating temperatures between 500 and 750°C. They, therefore, complement Sandvik's existing ferritic and austenitic high temperature grades, Sandvik 4C54, Sandvik 253MA™ and Sandvik 353MA™, designed for use at operating temperatures from 800 to 1,175°C in reducing sulphurous and in oxidising service conditions.

Grade 2C48 is designed for use in sootblower lance tubes in the boiler industry and also for pyrometer tubing. Its ductility makes it particularly suitable for cable tubing for furnace temperature measuring systems.

Sandvik is producing tube and pipe in the new grades in a full size range between 20 and 70 mm outside diameter.
