Finishes 1 - Stainless steel finishes 1,2 Mill Finishes Mechanically Polished andBrushed Finishes (e.g.420).Scaling avoided by Similarly,stainless steels offer a wide range of surface finishes which can assist the architect in achieving the aestheticallyMARTENSITIC STAINLESS STEELmartensitic stainless steels should not be used above 800 °F (425 °C) due to loss of strength and corrosion resistance.AK Steel produces eight martensitic grades tailored for a variety of property requirements and applications.Applications for the martensitic stainless steels include cutlery,cookMachinability of Hard Martensitic Stainless Steel andparameters as that of stainless steel.It indicates that the plastic deformation by stainless steel is more than alloy steel.Figure 3 (a),(b),(c) and (d) is the graphical representation of roughness against cutting velocity for both CBN and PCBN tools for stainless steel and SCM 440 alloy steel.

According to their crystalline structure,stainless steels are divided into martensitic,austenitic and ferritic steels.A combination of martensitic and ferritic steels forms a fourth group known as precipitation-hardened steels.Grade 420F stainless steel is a general purpose free machining version of 420 stainless.

It can be hardened to Rockwell 58 hardness,making it one of the hardest stainless steels.Also known as razor blade steel.Available in three grades 440A,Stainless Steels EDROEDRO400 is a remelted 400 series martensitic stainless steel supplied prehardened to approximately 40 HRC (375 HB).EDRO400 was developed as an improved stainless grade providing excellent polishability combined with good corrosion resistance,consistent hardness,enhanced machinability,superior dimensional stability,and good ductility Stainless steel grade chart holder in China,we provide the best prices,quality,support,and quick delivery time.Stainless steel sheet can be provided with mill finish,polished.Standard:ASTM A240,JIS G4304,G4305,GB/T 4237,GB/T 8165.Materials 400series:409,409L,410,420,430,431,440; Other Stainless Steel and Alloy material.Thickness Cold Rolled:0.03mm-6mm

Surface Hardening of Stainless Steels

hardening of steels are shown in Table 1.These long-established techniques are continually improved and remain among the most widely applied ones.This publica-tion discusses the most important surface-hardening methods used on stainless steels (marked in italics in the following table).2 Principle SURFACE HARDENING OF STAINLESS STEELSUnderstanding Wear and Friction in Medical-Grade Stainless Aug 01,1999·Magnetic in the annealed and hardened conditions,these materials are not as corrosion resistant as the other categories of stainless steels.Types 420 and 440C are often used for surgical cutting instruments,drills,and reamers.Precipitation-hardening (PH) stainless steels have properties between those of the martensitic and austenitic types.Hardness is developed by a solution heat
