Product Description
1.5714 637M17 EN351 Hot Rolled Engineering Round Steel Bar
1: DIN 16NiCr4 Steel Introduction
16NiCr4 Alloy steel is a low carbon case hardening steel which has at least 0.6Cr%,0.8%Ni as strengthening elements. It has a low-medium hardenability with good core resistance up to a thickness of about 50 mm, and has a good machinability in the annealed condition.16NiCr4 is generally supplied in the annealed condition with Max hardness 217HB.

7: DIN 16NiCr4 Steel Application
16NiCr4 Alloy steel is a case-hardening steel widely used for high-strength core parts, structural parts subject to abrasion and variable loads typically used for small-sized parts, such as loaded gears, screws, pins, shafts, pivots, machine parts, cars and engines.
8: DIN 16NiCr4 Steel Heat Treatment
Forging
16NiCr4 Alloy steel forging temperature: 900 – 1150°C, cooled as slowly as possible in still air or in the sand after forged.
Heat Treatment
Normalizing: 870 – 890°C, Cooling in air
Soft Annealing: 680 – 720°C, Cooling in the furnace
Carburizing: 880-980°C
Core-hardening: 850-890°C, oil-polymer salt bath
Case-hardening: 780-820°C, oil-polymer salt bath
Carbonitriding: 860-930°C/Gas
Tempering: 150-200°C
Surface Hardness
Treated to improve wearability(+S): Max 255HB
Soft annealed(+A): Max 217HB
Treated to hardness range(+TH): 166-217HB
Treated to ferrite-pearlite structure and hardness range(+FP): 156-207HB

10: Delivery condition
The delivery condition is usually hot forged or rolled, annealed/QT, rough turned/Black surface and hot rolled, annealed/QT, Black surface for hot forged rolled bar and hot forged or hot rolled bar.
But for hot forged or hot rolled plate, usually the delivery condition is hot forged, annealed/QT, milled surface/Black surface or hot rolled, annealed/QT, black surface.
