Heat Treated HOT ROLLED COLD FINISHED PACIFIC MOLY KROME is available in four conditions heat treated quenched and tempered annealed normalized and as rolled It is a widely used medium carbon alloy steel which is relatively inexpensive considering the hardenability it offers 176 F prior to hot mechanical working such as forging for a long period a deterioration in the room temperature mechanical properties particularly tensile ductility and impact strength or toughness can be obtained after the steel has been given a final heat treatment comprising reaustenitizing quenching and tempering Ref 1 3

Jul 26 32 The fractions of austenite and martensite can be controlled by this interrupted quenching process After quenching the steel is usually reheated to a higher temperature partitioning temperature and held for a couple of minut In a typical steel alloy the supersaturated carbon in martensite would lead to cementite precipitationJul 29 32 The process of quenching and tempering carbon steel tubulars is not unlike that which is applied to other carbon steel shapes the part is heated to about 1 600 degrees Fahrenheit cooled rapidly and reheated to a temperature less than about 1 300

Jan 05 32 I am making a roller metal spinning tool The roller will look a lot like a wheel from an in line skate and will run on two ball bearings The material is steel The tool is for low quantity steel spinning work so exotic metals are not required for the roller I want to heat treat the wheel to What is the difference between quench and tempered steel and hot rolled steel 1 2 3 is rolling technique blunts are rolled but the process of rolling a good jay is more like folding

For this process hot rolled coils or bars are drawn through a forming die which elongates the steel decreasing diameter and increasing product length The material is then straightened to tolerance and cut or sheared into desired length toleranc After thorough testing finished bars are weighed banded and tagged to customer specificationJul 13 32 Making an improper selection of steel for the process Too much time between the quenching and the tempering of the heat treated parts A common misconception is that quench cracks can occur only while the piece is being quenched This is not true If the work is not tempered right away quench cracks can and will occur Improper design

Sep 11 32 Customers often ask us about the differences between hot rolled steel and cold rolled steelThere are some fundamental differences between these two types of metalThe differences between hot rolled steel and cold rolled steel relates to the way these metals are processed at the mill and not the product specification or gradeJul 13 32 Making an improper selection of steel for the process Too much time between the quenching and the tempering of the heat treated parts A common misconception is that quench cracks can occur only while the piece is being quenched This is not true If the work is not tempered right away quench cracks can and will occur Improper design
