Mayari PIG [RON 42 heat-resisting Castings By rue vse of a small percentage of Mayari Pig Iron in the cupola mixture, grate-bars and other furnace parts can be given much longer life at a trifling increase in cost. Mayari is a natural nickel-chromium pig iron and offers a simple, eco- nomical means of introducing those elements to make heat-resisting alloy-iron castings. Mayari is also an effective agent for improving castings for machinery parts. Machinability, sound- ness, strength and wear-resistance are all substan- tially improved by a small Mayari addition. Engine and pump cylinders, piston rings and similar parts ean be cast with assurance of freedom from blow- holes, can be machined at lower cost, and will last longer, if Mayari is used. Let one of our foundry specialists discuss the ap- plication of Mayari to your uses. A ’phone call or letter to the nearest Bethlehem district office will bring him.

A known product sells with less sales effort because buyers have confidence in an advertised product. Non-adver- tised products are strangers to be doubted. Don’t handicap your business by fail- ing to properly advertise your products. MARINE REviEw—October, 1934
