Material compatibility is a crucial consideration when selecting a plate rolling machine, as different metal grades exhibit varying yield strengths, elongation properties, and work-hardening characteristics during the rolling process. RAYMAX’s plate rolling machines work on sheet metals such as steel, aluminum sheet, and stainless steel sheet as long as the thickness is targeted for your machine production. Our range of machines addresses various thicknesses and types of materials which demands the diversity of production. For carbon steel grades including A36, A516, S235, and S355 with yield strengths up to 345 MPa, our rolling machines provide reliable forming for structural and pressure vessel applications. For stainless steel alloys such as 304 and 316L, which have yield strengths of approximately 520–700 MPa, careful control of rolling parameters is required to prevent work hardening and surface marking. The rolling capacity for stainless steel is typically 30-50% lower than for carbon steel due to higher yield strength and increased spring-back tendency. For aluminum grades including 5052 and 6061, which have lower yield strengths (approximately 200–300 MPa), the rolling capacity is higher than for steel of equivalent thickness, but careful control is required to prevent surface marking from roll contact. Pre-bending thickness typically reaches 70-80% of maximum rolling thickness on most materials, an important specification for applications requiring minimal flat residual edges before seam welding. For high-strength alloys used in aerospace components and pressure vessels, hydraulic rolling systems provide the precise pressure control necessary to achieve tight radius tolerances while preventing material cracking or delamination. The rolling radius is equal to the roller diameter minus half the thickness of the plate. The maximum allowable longitudinal strain can be estimated by dividing the material’s yield strength by a safety factor. Understanding these material-specific capabilities helps fabricators select equipment that reliably meets their production requirements. RAYMAX’s product lineup includes 3-roll and 4-roll bending machines, with capacities ranging from 1mm to 200mm thickness, ensuring compatibility with applications in HVAC, automotive, and structural engineering. Our rolling machines are ideal for use in automotive, shipbuilding, power generation, and other industries.
