With the exploration and innovation of Bebon people, DEN gradually formed four major advantageous products: steel plate, steel pipe, stainless steel, special steel, and established our own Machining processing center in order to meet customer's diverse requirements.




Quenching Heat Treatment Specialty Steel Treating

Bright Hardening. Bright hardening is applied to certain tool or stainless steel parts where heating is in an inert atmosphere and quenching to full hardness is not necessary. Therefore, parts will result in a bright

Bright TemperingAchieving High Quality Appearance

This paper will also present data collected from tests run on the bright tempering of sensitive alloys such as PH 17 4 (X5CrNiCuNb 16 4), Inconel 718 and 420 stainless steel (X42Cr13) that yielded bright, clean and uniform parts. Introduction. Imagine trying to temper your materials above a charcoal or coal forge, or even by fire.

How To Passivate Stainless Steel Parts Modern Machine Shop

Oct 01, 2003 · If cutting fluids are allowed to remain on parts that are bright hardened, as in a vacuum furnace or protective atmosphere, surface carburization may occur, leading to a loss of corrosion resistance. Passivating Baths. After thorough cleaning, the stainless steel part is ready for immersion in a passivating acid bath.

Heat Treatment of SteelsHardening, Tempering, & More

Hardening Hardening involves heating of steel, keeping it at an appropriate temperature until all pearlite is transformed into austenite, and then quenching it rapidly in water or oil. The temperature at which austentizing rapidly takes place depends upon the carbon content in the steel used.

Hardening 304 & 316 stainless steel (Austenitic)

A. Austenitic stainless steels are capable of some surface hardening, but not through hardening treatments like quench & temper. Bodycote has a process called Kolsterising that diffuses carbon & nitrogen into the surface for increased hardness, wear resistance, etc. I recommend you contact them for more information.

Bright Annealing Stainless Steel & Metal Services

Bright Annealing Services Annealing is an integral part of making materials soft as possible, increase ductility and less brittle. The annealing process reduces the hardness and makes the material easier to machine and can be used on stainless steel, cobalt, chrome, high temperature alloys and titanium.

How heat treating and annealing stainless steel Paulo

Precipitation hardening stainless steels are “aged,” a heating process that occurs after annealing to create new phases in parts to increase their strength. The 17 4 grade is unique in that it shrinks during precipitation hardening—the opposite of most other steels, which are at risk of distortion due to expansion during treatment.
