slightly better corrosion properties. Its corrosion resistance properties are similar to 410 stainless steel, with optimum corrosion resistance of 440B achieved with a temper below 400°C. For 440B to achieve best corrosion resistance all surfaces must be

free of scale, foreign particles, lubricants and coatings applied for drawing and heading. With its high carbon content 440B

stainless steel annealed bar has similar machining characteristics to a high speed steel annealed grade.
