Harshita Stainless is a renowned manufacturer and supplier of Stainless Steel XM19 Bolts in Delhi, India. Renowned for their high strength, corrosion resistance, and durability, XM19 bolts are best suited for critical applications in marine, chemical, and aerospace industries. The bolts are non-magnetic, possess high yield strength, and are chloride stress corrosion cracking resistant. We at Harshita Stainless offer XM19 bolts in different sizes and thread types for precision, quality, and performance in demanding situations across India.
XM19 (Nitronic 50) bolts consist of 20.5% Cr, 11.5% Ni, 4.5% Mn, and 2–3% Mo, along with nitrogen for added strength. They provide yield strength of up to 690 MPa, approaching twice that of 316, and tensile strength of approximately 900 MPa. They are non-magnetic and very corrosion-resistant, particularly in seawater and chemical environments, and maintain mechanical properties even at sub-zero temperatures. These bolts are weldable and machinable with ease

These bolts feature a looped head, ideal for lifting and securing applications. They offer excellent strength and corrosion resistance, making them suitable for marine and industrial use.
Designed with a rounded head and square neck, they prevent rotation during installation. These bolts are commonly used in wood and metal applications due to their durability and resistance to wear.
These bolts come with an integrated flange to distribute load evenly. They are ideal for high-pressure applications, providing excellent grip and resistance to corrosion in harsh environments.
Featuring a larger head for greater torque, these bolts are suited for heavy-duty applications. They provide exceptional strength and are commonly used in construction and machinery.
With a flat, countersunk head and long threaded shaft, they are ideal for conveyor systems and elevator belts. Their superior corrosion resistance ensures long-lasting performance.
Fully threaded bolts suitable for through-hole applications. They are versatile and reliable for assembly projects requiring strong and durable fasteners.
XM19 Bolts find widespread application in marine, aerospace, offshore platforms, chemical processing, and pulp & paper industry. Due to seawater corrosion resistance, they are suitable for ship construction and desalination plants. In aerospace applications, they find application in highly strength-requiring structural joints. In chemical plants, XM19 bolts protect against corrosion by aggressive media. Harshita Stainless provides XM19 bolts throughout Delhi and India, relied upon for high-load and high-corrosion applications where regular stainless fasteners are not up to the task.
