GUIDE TO SELECTION- PLATES

LOW CARBON STEEL PLATE

HR CARBON fromRyerson is an economical, general purpose steel for a wide variety ofapplications. 5/8” and lighter is held to a .25 max. carbon; over 5.8” platehas a carbon range of .10 to .33.

AISI 1015 isstocked in thicknesses ¾” and under for the best forming and weldingcharacteristics. A good general purpose plate with predictable qualities.

AISI 1020 isstocked in thicknesses to ¾” to 1 ½” inclusive. The higher carbon rangeimproves machinability while keeping good formability and weldability.

AISI 1025 –Plates over 1 ½” thick in this category are silicon killed along with havingthe higher carbon range for greater strength. This produces the optimumcombination of strength, weldability and good surface quality after machining,plus internal soundness.

MEDIUM CARBON STEEL PLATE

AISI 1045 –Silicon killed with higher carbon content for greater strength. In the lighterand medium thicknesses, heat treatment will provide still higher strength.Machinability is good. Forming and welding opportunities are limited.Identification color: yellow.

HIGH CARBON STEEL PLATE

FH “62” FINELINE (1060) – A special quality fine grainedfully killed steel plate with a carbon content of .55/.66 for greater strength.Flame and induction hardens to 62 to 66 Rockwell C in depths to ¼”. Spherodizeannealed for excellent machinability with minimum distortion. Produced by theFineline process with reduced sulphur levels (.010 max.) which further improvesthe internal soundness and toughness, along with reducingthe possibility of lamellar tearing. Popular for machine ways, gibs, rails,slides, wear strips and tooling applications. Our precision machines will cutto size without impairing the fine metallurgical properties of this steel.Identification color: yellow and pink.
