Powder-actuated fasteners are made of special heat-treated steel. Common nails are not used for powder-actuated fastenings.
Powder-actuated tool - Wikipedia
There are many specialized fasteners designed for specific applications in the construction and manufacturing industries. Powder-actuated technology was developed for commercial use during the Second World War , when high-velocity fastening systems were used to temporarily repair damage to ships. In the case of hull breaches, these tools fastened steel plates over damaged areas. Fasteners take various forms, for example with threaded ends to use as an embedded bolt, with washers at the tips that grip softer material etc.
Fasteners used in powder-actuated tools are manufactured from special steel and heat-treated to produce a very hard yet ductile fastener. Those properties are necessary for the fastener to penetrate concrete or steel without breaking. Powder-actuated tool cartridges are specially-designed blank firearm cartridges. In many cases, the charges are ordinary firearm cartridges with modified casings, and the bullets removed.

These charges may be hand-fed, or manufactured and distributed on a plastic strip. The charges are activated when a firing pin strikes the primer, which is an explosive charge in the base of cartridge. The primer ignites the charge, which burns rapidly.
The gases released by the burning of the propellant build pressure within the cartridge, which acts either on the head of the nail, or on the piston, accelerating the nail towards the muzzle.

As with their air-actuated cousins, powder-actuated guns have a muzzle safety interlock. If the muzzle is not pressed against a surface with sufficient force, the firing pin is blocked and cannot reach the load to fire it. This ensures that the gun does not discharge in an unsafe manner, causing the nail to become a projectile. Most manufacturers of powder-actuated nail guns offer training and certification. Many projects and employers require this before an employee is permitted to use the tool.
The ownership and use of these tools is regulated in Australia. The owner has to register the tool, and an operator of one of these tools is required to have a license and to have undergone training in their use. These laws are in keeping with Australia's extremely strict firearm laws. OSHA prohibits using a powder actuated tool unless the user is trained and licensed. In addition, special instruction is necessary if unable to distinguish colors used in the color code system that identifies proper power levels.
