Stainless steel rivet is made of special steel wire as raw material according to forging, hardening and heat treatment process. It can show good riveting properties in a wide range of applications. Unique materials

-Martensitic stainless steel rivet - used for riveting stainless steel plate with low strength;

-Austenitic stainless steel rivets - stainless steel plates with high strength that cannot be joined with martensitic double drum stainless steel rivets;

-Copper bolts - used to rivet unique plates, such as red copper, red copper and plastic plates;

-Aluminum bolts - used for riveting aluminum plates with low strength. Bolt strength

Bolts are manufactured according to different strength levels to consider the riveting requirements of different riveted plates. Generally speaking, the strength of the bolt increases with the thickness and / or strength increase of the riveted plate. To determine the available bolt strength and appearance.

The forging, hardening and heat treatment process of the bolts ensure the good riveting characteristics of stainless steel rivets. The strength of heat treatment process is controlled in the middle of hrc45 ~ 56. The bolts are generally made of high carbon steel. I really don't know that 45 steel is used as bolt, and there are heat treatment process regulations.

If you use hot riveting, what is the significance of the front heat treatment process? If cold riveting is used, can such high strength riveting be achieved? There are many ways of connection, such as shaft pin, high strength bolt and reamed bolt. The heat treatment process can be solved immediately to this strength, but very few of them have the high toughness of 45

It is very likely to choose nitriding or induction quenching. Quenching oil is not effective. Even if the strength of iron rivets is achieved, it is too brittle and very easy to break. It is very difficult to heat treat 45 steel beyond 50 degrees, unless a unique method is selected. Hb250-285 is OK. It is very difficult to rivet with such high strength

Only nitriding can achieve this strength, but parts such as too careful strength is also a problem

It should not be too difficult to achieve this surface strength by nitriding.
