Special steels of materil handling
Special steel is added alloying element (NI,Cr,Mo and so on) for the purpose. To mainly, it is used for parts of cars, metal, cutting tools, airplane, rocket and domestic articles. As a function, toughness, abrasion resistance property, heat-resistant and corrosion-resistant etc. We handle polish, cold-rolling and hot-rolling. Steel types ex)S45C・S55C・S60C・S65C・SAE1060・SAE1070・SK85(SK5)・SUJ2・SCM415・N22CB・N63C・NKS56・SUP6 In case of there is not on the inventory as follows, please feel free to contact us.

Iron is changing the features by adding various elements. JIS steel type is unsatisfied … please contact us like this request.
standard | peculiarity | comparison | difference | application ex |
---|---|---|---|---|
N35CB | Excellent in high processability and hardenability | S35C | By adding Boron, improvement for hardenability | drive plate・sheet gear |
NK7Cr | Steel for cutting tools including high toughness | SK7 | By adding low-C and Cr, improvement shock resistant and toughness | Solid saw・Tip saw |
NK6DCr | Steel for bearing which is excellent in abrasion resistance property | SPCC cementation | surface cement to all cement | bearing |
NK6Cr | toughness, abrasion | |||
NKS80 | anisotropy and soften resistance improvement steel | SK5 | improvement for toughness by MO addition and inclusion control | Integrated Cushioning Plate Tip Saw |
NKS85 | soften resistance of SK55 and toughness improvement steel | SKS5 | improvement for abrasion resistance property and toughness by Mo,V addition | Hair Clipper Blade・rice reaping cutting |
NKS90 | toughness, high fatigue characteristic steel | SK7 | It adds Mo into NKS62 of steel for cutting tools. improvement for abrasion resistance property | band saw |
NCH780 | low carbon 780N high tensile steel | Don’t need hardening normal steel to VA proposition steel |

NK6Cr | toughness, abrasion | SUP7 | fatigue strength is up by C%up ,Mo addition | diaphragm spring・diamond saw basal plate |
NFBS150 | high strength steel for FB | S45C | It has controlled a cooling by hot-rolling, with the result that it gets 100%share surface | Driven plate |
It is effective cost down!
There is a way of consideration which is a challenge. For example, we must consider what should we do to increase sales, benefits and suggestions.
In the case of up or down 10-20%, it might be possible to do it by conventional methods, but in the case of 50%, it must change the methods radically, otherwise it cannot settle the matter.
There are the following examples by using the previously mentioned N35BC etc.
Case example | Each kind of gears |
---|---|
trend | steel bar to special steel sheet |
effect | heat treatment |
usual process | round bar forging→annealing→cutting→heat processing |
improvement process | steel sheet punching→heat treatment |
This is an example which connect to the process omission by changing round bars to sheet materials. There are potentialities much more around everyone.
Let’s thinking! We will support for you.
ベーナイト鋼
Bainitic steel
Bainite is a structure that is maintained by less than A3 transformation point temperature and it is called Bainite upper and lower sides together. Bainite is essentially similar to hardening and tempering structure, but it is superior to toughness and processing compared to hardening and tempering structure. About JIS steel type, S55C-CSPB, S60C-CSPB,SK5-CSPB etc. The title is different depends on makers. We keep in stock of bainite of NISSHIN STEEL MANUFACTURE CO.,LTD. Steel type code is NBS55 and NBS60
As a future of Bainite … excellent in processability. Bainite structure is superior to processability and strength by isothermal transformation processing. Bending method was difficult in conventional methods, but now it is possible slightly.
For details, please observe our inventory.

ステンレス鋼
Stainless steel
Stainless is a steel which is corrosion-resistant including more than about 11% Cr. SUS(Steel Special Use Stain-less) We mainly handle with stainless for springs. The others we handle with stainless mirrors as well.
