Definitions

  • the invention relates to a hot strip of steel of high strength which is at most 5 mm thick and to a method for its production.
  • Hot strip means hot-rolled strip.
  • hot strip is only manufactured up to strengths of around 800 N / mm 2 . These are thermomechanically rolled micro-alloyed steels. For applications that require additional strengths, soft hot strip is used and the strength required on the component is set by a subsequent heat treatment. For the thickness range below 2.0 mm, additional cold rolling is usually required to set the desired thickness. The required strength is also set in this case by a suitable heat treatment.
  • a high-strength and tough steel with good machinability which consists of 0.005 to 0.3% C, 0.3 to 2.5% Mn, up to 1.5% Si and at least one carbide and nitride former the group contains Nb, V, Ti and Zr in amounts of up to 0.1%, up to 0.15%, up to 0.3% and 0.3% respectively.
  • this steel is quenched in such a way that it contains 5 to 65% ferrite, the remainder being martensite.
  • the production of wires and rods is particularly important.
  • AI From GB 2 195 658 AI are forgings made of steel with 0.01 to 0.20% C, up to 1.0% Si, 0.5 to 2.25% Mn, up to 1.5% Cr, up to 0, 05% Ti, up to 0.10% Nb, 0.005 to 0.015% N and up to 0.06% AI known.
  • the cooling of the steel from the austenite area should be controlled so that the structure is fully martensitic.
  • carbon contents below 0.10% and silicon contents above 0.17% are disclosed.
  • the sulfur content is relatively high at over 0.01%.
  • the steels known from EP 0 072 867 AI also have carbon contents below 0.10% and silicon contents above 0.15%. After broken cooling, the hot strip has a dual-phase structure made of polygonal ferrite and a mixture of pearlite and bainite.
  • the hot strip known from DE 30 07 560 AI is cooled after hot rolling at a cooling rate of 1 K / s or faster to produce a dual-phase structure made of ferrite and martensite.
  • carbon contents in the range of 0.02 to 0.09% are recommended.
  • the preferred silicon content is relatively high at 1.0%.
  • the invention has for its object a hot strip with tensile strength values above 800 N / mm 2 and at the same time good cold formability in the thickness range ⁇ . 5 mm.
  • a hot strip with a thickness of less than 5 mm, in particular less than 2 mm is proposed according to the invention, which has a tensile strength of 800 to 1400 N / mm 2 , from a steel of the following composition (in mass%):
  • Remainder iron and unavoidable impurities including up to 0.015% phosphorus and up to 0.003% sulfur, and martensitic structure with less than 5% in total of other structural components.
  • the steel can optionally additionally contain at least one of the following elements in mass%: up to 1.0% chromium, up to 0.1% copper, up to 0.5% molybdenum, up to 0.1% nickel, up to 0.009% nitrogen.
  • Carbon can preferably be contained from 0.08 to 0.15%, manganese from 1.75 to 1.90%, chromium from 0.5 to 0.6% and nitrogen from 0.005 to 0.009%.
  • a method for producing hot strip with a final thickness of less than 5 mm, in particular less than 2 mm, from a steel of the claimed composition with tensile strength values above 800 N / mm 2 comprises the following measures:
  • a slab is heated to 1000 to 1300 ° C, pre-rolled in the temperature range from 950 to 1150 ° C and finish-rolled at a final rolling temperature above Ar3, the hot strip produced in this way is heated to a coiling temperature in the range from 20 ° C to below the martensite start temperature for conversion cooled and coiled into a martensitic structure with a total content of other structural components of less than 5%.
  • the Ar3 temperature can be estimated using the following equation:
  • Ar3 910-310x (% C) -80x (% Mn) -20x (% Cu) -15x (% Cr) -55x (% Ni) -80x (% Mo)
  • the martensite start temperature Ms can be estimated using the following equation:
  • Ms 500-300x (% C) -33x (% Mn) -22x (% Cr) -17x (% Ni) -11x (% Si) -11x (% Mo>
  • the tensile strength of the hot strip is preferably set to a value in the range from 800 to 1400 N / mm 2 by appropriate selection of the reel temperature within the aforementioned temperature range.
  • the hot strip can be hot-dip galvanized to become more corrosion-resistant. Easily cold-formable, high-strength galvanized sheets are preferred for mechanically highly stressed components in automobile construction, for example for side impact beams and bumpers.
  • the steel according to the invention achieves high strength without expensive alloying elements and without annealing treatment as is the case with known steels.
  • a steel with 0.15% C, 0.01% Si, 1.77% Mn, 0.014% P, 0.003% S, 0.028% Al, 0.0043% N, 0.526% Cr, 0.017% Cu, 0.003% Mo , 0.027% Ni, remainder Fe was cast into a slab.
  • the slab was reduced to approx. Warmed up to 1250 ° C, at approx. Pre-rolled at 1120 ° C and rolled to a final thickness of 2 mm at a final temperature of 840 ° C, then cooled and coiled at 50 ° C. This creates a structure with more than 95% martensite.
  • the yield strength reached values of 1120 N / mm 2 and the tensile strength values of 1350 N / mm 2 with elongation values A B0 to 11.1%.
  • Example 1 A steel with the same analysis as in Example 1 was processed into 3.5 mm thick hot strip. The data are reported in Table 1. The strength values are significantly higher when reeling instead of over 400 ° C to 95 ° C. Table 1
  • the hot strip can be hot-dip galvanized into the final shape before cold forming.
  • the martensite is left on by the heat treatment cycle during galvanizing.
  • tensile strengths in the range of 1200 - 1400 N / mm 2 , depending on the heat treatment cycle, tensile strengths between 800 and 1100 N / mm 2 are established during galvanizing.
  • Table 4 shows the corresponding data for 1.4 mm thick
